It is shown that the Kerr metric represents the nonlinear superposition of self-dual and anti-self-dual Taub-Newman-Unti-Tamburino (NUT) instantons. This promotes the Newman-Janis algorithm to a rigorous derivation of the Kerr metric with a definite physical origin. In the same way, the Kerr-Newman and charged Kerr-Taub-NUT solutions are systems of Taub-NUT instantons and chiral dyons.

Emergent collective excitations constitute a hallmark of interacting quantum many-body systems, yet in solid-state platforms their study has been largely limited by the constraints of linear-response probes and by finite momentum resolution. We propose to overcome these limitations by combining the spatial resolution of ultracold atomic systems with the nonlinear probing capabilities of two-dimensional spectroscopy (2DS). As a concrete illustration, we analyze momentum-resolved 2DS of the quantum sine-Gordon model describing the low-energy dynamics of two weakly coupled one-dimensional Bose-Einstein condensates. This approach reveals distinctive many-body signatures, most notably asymmetric cross-peaks reflecting the interplay between isolated (B_{2} breather) and continuum (B_{1} pair) modes. The protocol further enables direct characterization of anharmonicity and disorder, establishing momentum-resolved 2DS as both a powerful diagnostic for quantum simulators and a versatile probe of correlated quantum matter.

EXO-200 was a leading double beta decay experiment consisting of a single-phase, enriched liquid xenon time projection chamber filled with an admixture of 80.672% ^{136}Xe and 19.098% ^{134}Xe. The detector operated at the Waste Isolation Pilot Plant between 2010 and 2018 and was designed to search for double beta decay of ^{136}Xe. Data were acquired in two phases separated by a period of detector upgrades. We report on the search for 0νββ and 2νββ decay of ^{134}Xe with Phase II EXO-200 data, with median 90% CL exclusion sensitivity to half-life T_{1/2}^{0ν}≥3.7×10^{23}  yr and T_{1/2}^{2ν}≥2.6×10^{21}  yr, respectively. No statistically significant signal is observed for either decay mode. We set a world-leading lower limit on the half-life of the neutrinoless decay mode of ^{134}Xe of T_{1/2}^{0ν}≥8.7×10^{23} (90% CL) and the second strongest constraint on the two-neutrino decay of T_{1/2}^{2ν}≥2.9×10^{21} (90% CL), a threefold improvement over the EXO-200 Phase I measurement. New constraints are also set for the 2νββ and 0νββ decays of ^{134}Xe to the lowest excited state of ^{134}Ba.

We investigate the time dependence of antiflatness in the entanglement spectrum, a measure for nonstabilizerness and lower bound for nonlocal quantum magic resource, on a subsystem of a linear SU(2) plaquette chain during thermalization. Tracing the time evolution of a large number of initial states, we find that the antiflatness exhibits a barrierlike maximum during the time period when the entanglement entropy of the subsystem grows rapidly from the initial value to the microcanonical entropy. The location of the peak is strongly correlated with the time when the entanglement exhibits the strongest growth. This behavior is found for generic highly excited initial computational basis states and persists for coupling constants across the ergodic regime, revealing a universal structure of the entanglement spectrum during thermalization. We conclude that quantitative simulations of thermalization for non-Abelian gauge theories require quantum computing. We speculate that this property generalizes to other quantum chaotic systems, a conjecture supported by analogous behavior observed in real-time simulations of the mixed-field Ising model.

Due to the Coulomb blockade effect, electrons typically tunnel into a localized state one by one, showing antibunching behavior. However, theory predicts that strong vibronic coupling can generate electron bunching locally, yet direct atomic-scale evidence has remained elusive. In this Letter, we report an atomically resolved shot-noise study probing the transport statistics of single-electron tunneling in an atomic impurity coupled to a vibrational mode. Conventional time-averaged conductance spectroscopy reveals clear signatures of vibron-assisted tunneling in this atomically sized nanoelectromechanical system. Simultaneous shot-noise measurements at the impurity center show super-Poissonian noise, providing direct evidence that vibronic coupling drives electron bunching during tunneling. As a future outlook, if coherence between electrons can be implemented, vibron-mediated electron bunching at single atomic sites may be exploited as a local injection source of N-paired electrons.

Fission and fusion of lipid membranes are ubiquitous shape transformations in living cells, necessary for maintaining the shape of organelles and enabling a host of transport processes between them. These topology-changing events involve curvature-elastic free energy changes proportional to the Gaussian curvature modulus, κ[over ¯]. However, precisely because of its topological nature, the value of this modulus is exceptionally hard to determine. Here we propose a novel method to computationally determine κ[over ¯] that involves simulating triply periodic minimal surfaces. We measure their excess curvature energy E and infer the associated free energy F via a thermodynamic argument that rests on the strong temperature dependence of E and the relatively weak temperature dependence of E/F. Our approach is unique in that it circumvents the complications arising in alternative procedures that require an open membrane edge to break the constraints of the Gauss-Bonnet theorem. As an illustration, we determine κ[over ¯] for a coarse-grained lipid model over a range of temperatures and lipid shapes. We show that the observed changes of both the Gaussian curvature modulus as well as its ratio to the ordinary bending modulus follow widely held expectations.

Nuclear mass is a key indicator of how the nuclear shell structure evolves. The recent mass measurement study of neutron-rich lanthanum isotopes [Jaries et al., Phys. Rev.

The recent mass measurement study of neutron-rich lanthanum isotopes [Jaries et al., Phys. Rev. Lett. 134, 042501 (2025)PRLTAO0031-900710.1103/PhysRevLett.134.042501] reveals the presence of a distinct prominence in their two-neutron separation energies. However, its presence has been called into question based on the results of another mass determination [Liu, Ph.D. thesis, University of Notre Dame, 2025, 10.7274/28766600.v1.]. In this Letter, we report an effort to clarify these contradictory results through the use of the simultaneous mass-lifetime measurement of the neutron-rich lanthanum isotope ^{149}La using a multireflection time-of-flight mass spectrograph combined with a β-TOF detector. The peak corresponding to a β-decaying state was observed in the time-of-flight spectra at a position of 221(6)  keV/c^{2} lighter than the reported ^{149}La mass in Jaries et al., but our measured result is in excellent agreement with the mass value reported in Liu. We have concluded that this peak is the ground state of ^{149}La. With this, the previously reported distinct prominence in the two-neutron separation energies disappears, while a new kink structure, similar to that in the cerium isotopes, appears. Comparison with theoretical models suggests that a nuclear shape transition from octupole deformation to another type of deformation occurs around N=91 and is likely the cause of this kink structure.

The equations of classical mechanics can be used to model the time evolution of countless physical systems, from the astrophysical to the atomic scale. Accurate numerical integration requires small time steps, which limits the computational efficiency-especially in cases such as molecular dynamics that span wildly different timescales. Using machine-learning (ML) algorithms to predict trajectories allows one to greatly extend the integration time step, at the cost of introducing artifacts such as lack of energy conservation and loss of equipartition between different degrees of freedom of a system. We propose learning data-driven structure-preserving (symplectic and time-reversible) maps to generate long-time-step classical dynamics and show that this method is equivalent to learning the mechanical action of the system of interest. These models can be learned based on short reference trajectories and be transferred across thermodynamic conditions and chemical composition. We show that an action-derived ML integrator eliminates the pathological behavior of non-structure-preserving ML predictors and that the method can be applied iteratively, serving as a correction to computationally cheaper direct predictors.

We present a real-time quantum Monte Carlo algorithm that simulates the dynamics of open quantum systems by stochastically compressing and evolving the density matrix under both Markovian and non-Markovian master equations. Our algorithm uses population dynamics to continuously suppress the sign problem, preventing its accumulation throughout the evolution for a broad class of noisy-circuit Liouvillians of practical and experimental interest. We apply it to a variety of quantum circuits and demonstrate significant speedups and scaling improvements over state-of-the-art quantum trajectory methods and convergence to exact solutions even in non-Markovian regimes where trajectory methods fail. Our approach improves the efficiency of classical simulation of gate-based quantum computing, quantum annealing, and general open system dynamics.

Extended, localized, and critical states form the three elementary classes of eigenstates underlying Anderson localization. While phases involving extended and localized states are widely studied, experimental realization of critical phases, particularly those where critical states coexist with others, remains a challenge. Here, we report to realize five distinct localization phases: extended, localized, critical, extended-localized mixed, and critical-localized mixed, in a one-dimensional Floquet lattice with quasiperiodic hopping amplitudes and on-site potentials. These phases are identified through characteristic spatiotemporal dynamics, supported by mutually consistent experimental observations and theoretical analysis. Our findings establish a unified experimental framework for systematic studies of localization transitions, mobility edges, and criticality in driven quasiperiodic systems.

We demonstrate a three-dimensional magneto-optical trap (MOT) of a metal hydride molecule, CaH. We are able to scatter ∼10^{4} photons with vibrational loss covered up to vibrational quantum number ν=2. This allows us to laser slow the molecular beam near zero velocity with a "white-light" technique and subsequently load it into a radio-frequency MOT. The MOT contains 230(40) molecules, limited by beam source characteristics and predissociative loss of CaH. The temperature of the MOT is below one millikelvin. The predissociative loss mechanism could, in turn, facilitate controlled dissociation of the molecule, offering a possible route to optical trapping of hydrogen atoms for precision spectroscopy.

The James Webb Space Telescope has uncovered a population of compact, high-redshift sources, the Little Red Dots (LRDs), which may host supermassive black holes (BHs) significantly heavier than their stellar content compared with local scaling relations. These objects challenge standard models of early galaxy formation and may represent an extreme class of early BH hosts. In this Letter, we investigate whether these BHs could have a primordial origin. We first show that the direct formation of these BH masses in the early Universe is excluded by stringent cosmic microwave background μ-distortion limits. We then investigate the assembly of massive BHs from lighter, observationally allowed primordial black holes (PBHs) via hierarchical mergers, finding that, although this channel can operate depending on the merger history, it faces challenges in explaining the observations due to the rarity of the required high-redshift dark matter halos. Finally, we estimate gas accretion onto intermediate-mass PBHs, while jointly tracking metallicity evolution, and identify regions of parameter space in which such growth could reproduce the observed properties of LRDs. As a special case, we focus on the strongly lensed source QSO1, whose extremely low metallicity and large mass provide a stringent test of these formation channels.

A quantum-mechanical description is presented for the three-body physics of shielded dipolar molecules, including a prediction of observable Efimov physics. Despite the anisotropic and long-range nature of the interaction, shielding enables a regime in which universality emerges already at the two-body level and extends to the three-body sector, where Efimov physics emerges. On the negative side of the scattering-length resonance, computed trimer binding energies display the characteristic scaling expected for Efimov states. Finally, the sudden approximation can be used to create trimer bound states, starting from positive energy trap states as a way to create or detect these molecular trimers. Moreover, the three-body parameter expressed in dipolar units is found to be universal.

A flavor-tagged time-dependent analysis of B^{0}→K_{S}^{0}μ^{+}μ^{-} decays is performed across the full dimuon mass range excluding the J/ψ and ψ(2S) resonance regions. The analysis uses proton-proton collision data collected by the LHCb experiment in 2011-2018 at center-of-mass energies of 7, 8, and 13 TeV, corresponding to an integrated luminosity of 9  fb^{-1}. The CP violation parameters are determined to be C=-0.13±0.32±0.04, S=+0.82±0.29±0.05, where the first uncertainties are statistical and the second are systematic. The results are consistent with the standard model prediction. This is the first experimental study of time-dependent CP violation in b→sℓ^{+}ℓ^{-} processes.

Covalent semiconductor crystals such as silicon and diamond have demonstrated ultralarge elastic strains at micro and nanoscales, enabling desired figures of merit for strain engineered electronic and optoelectronic devices. However, the underlying origin of their elasticity-whether it arises from pure lattice displacements or atomic rearrangements (defects or phase transformations)-remains unclear. Here, we directly observed in situ elastic-lattice responses of microfabricated single-crystalline silicon and diamond bridges at room temperature under uniaxial tensile loading by employing high-resolution transmission electron microscopy and four-dimensional scanning transmission electron microscopy. We quantified the distribution of deep-strained atomic coordinates in real time and mapped elastic lattice strains across the entire sample with sub-pixel-precision and a wide field of view, indicating pure lattice elongation without extended defects or phase changes. Additionally, we established a quantitative linkage between macroscopic strain and lattice deformation. This Letter not only elucidates the nature of ultralarge elasticity in covalent materials but also provides a guideline for intelligent design of silicon and diamond electronic and photonic devices with disruptive physical properties via deep elastic strain engineering.

We present the first computation of the complete two-loop, fully differential soft function describing the production of a heavy-quark pair in association with a color-singlet system at hadron colliders. This result constitutes one of the most complex soft functions known to date and it is obtained in closed analytic form for generic multidimensional kinematics. This allows us to obtain novel analytic results for the transverse-momentum-dependent and threshold soft functions in this class of processes. We further obtain a decomposition of the soft function into dipole and tripole color correlators, thereby supplying essential building blocks for processes involving a heavy-quark pair produced together with additional light jets at both hadron and lepton colliders. These results represent a key ingredient for advancing precision predictions for heavy-quark physics at the LHC.

We show that general relativity and other geometrical theories can be viewed as a degenerate Otto cycle with only heat-exchange legs in emergent gravity. Including work-producing legs yields controlled violations of local Lorentz invariance and energy-momentum conservation, which produce late-time cosmological acceleration. Implications for the cosmological constant problem, structure formation, and local observations are discussed.

Proper Theory of Magnon Orbital Angular Momentum at Equilibrium.

The orbital motion of chargeless bosons, unlike that of electrons, does not generate a magnetic moment and thus cannot directly interact with magnetic fields. To formulate the orbital angular momentum (OAM) of magnons, we first identify its proper conjugate variable by considering the Aharonov-Casher effect, which gives rise to a virtual perturbation to the equilibrium state, allowing us to calculate the magnon OAM as a virtual response to an infinitesimal electric field divergence. At finite temperatures, both self-rotation and topological contributions to the magnon OAM are explicitly derived, analogous to their electronic counterpart but with the correct bosonic statistics. In a two-dimensional honeycomb lattice, we show that the Dzyaloshinskii-Moriya interaction induces a large magnon OAM in both the ferromagnetic and antiferromagnetic phases. Our formalism can be generalized to other chargeless bosons with intrinsic spin.

The sensitivity of a mechanical transducer is ultimately limited by its inherent quantum fluctuations. Here, we use an optically levitated nanoparticle to measure impulsive forces smaller than the particle's zero-point momentum uncertainty. Our approach relies on reversibly squeezing the levitated particle's center-of-mass motion to coherently amplify the perturbation. We demonstrate an impulsive-force resolution as small as 6.9  keV/c, a value 0.6 dB below the sensor's zero-point value.

We present a search for an invisible hidden-sector particle X_{inv}, produced in B^{0}→D[over ¯]^{0}X_{inv} and B^{±}→hX_{inv} decays, where h=π^{±}, K^{±}, D_{s}^{±}, p^{±}. The search is performed using e^{+}e^{-} collision data recorded with the Belle detector, corresponding to 711  fb^{-1}. No significant signal is observed. We set 90% confidence level upper limits ranging between 10^{-4} and 10^{-6} on the branching fraction B(B→hX_{inv}) as a function of m_{X_{inv}}. Corresponding limits are set on B(B→hX)×B(X→γγ) for lifetimes cτ_{X} between 10  μm and 10 m. Many of these limits are the first direct constraints on their respective decays. Our results provide the most stringent exclusion limits to date on the branching fractions for all search channels, and exclude previously unexplored regions of parameter space relevant to several new physics models.
