This paper demonstrates that the real-time dynamics of entanglement measures under modular flow are governed by a unified generating function that uniquely determines chiral topological invariants, specifically the chiral central charge and Hall conductance, as validated by both free fermion models and chiral conformal field theory.
This paper demonstrates that incoherent electronic spectra across diverse strongly correlated materials arise from self-generated dynamical disorder and collapse onto a single universal curve described by a parabolic cylinder function, revealing a marginal dynamical regime where microscopic details become irrelevant at low energies.
This paper reports the first experimental observation of a macroscopic continuous spacetime crystal formed by active granular disks, revealing a unique three-stage melting process where spatial and temporal orders decay via distinct mechanisms, thereby demonstrating the decoupling of spontaneous symmetry breaking in space and time.
Using particle-based simulations, this study demonstrates that self-propulsion in active, non-Brownian suspensions can counteract friction-mediated shear thickening to induce a tunable "dethickening" effect, which follows a universal scaling framework based on dimensionless active stress.
This paper develops and benchmarks a modified Feynman variational method alongside other generalized analytical approaches to accurately describe lattice polarons in non-parabolic conduction bands across all coupling regimes, demonstrating superior agreement with numerically exact results compared to traditional continuum-based models.
This paper demonstrates that the transition between and superconducting states in a two-band model with nonmagnetic impurities evolves from a smooth crossover at high temperatures to a first-order phase transition at low temperatures, thereby establishing a critical end point on the temperature-impurity scattering rate phase diagram that suggests the possibility of a quantum phase transition.
Using large-scale Monte Carlo simulations, this study maps the finite-temperature phase diagram of the classical square-lattice Heisenberg-compass model, identifying six ordered phases and demonstrating that transitions between four symmetry-broken phases belong to the Ashkin-Teller universality class terminating at four-state Potts points, while transitions involving -polarized phases exhibit conventional 2D Ising criticality.
This paper identifies BiCuO(SO) as a rare two-leg quantum spin ladder featuring ferromagnetic rungs and exceptionally strong antiferromagnetic legs, a unique magnetic architecture confirmed through a comprehensive combination of experimental measurements and advanced theoretical simulations.
This paper demonstrates that a temporal Berry phase in a clean U(1) nonlinear sigma model induces space-time anisotropic vortex interference, leading to a quasi-disordered phase with short-range spatial order and persistent temporal coherence that shares the essential correlation properties of the disordered Bose Glass phase, thereby suggesting a unified topological origin for glassy behavior in phase-fluctuation-driven superfluid transitions.
Using molecular dynamics simulations, this study reveals that cylindrical confinement induces a two-stage collapse of homopolymers from a good to a poor solvent—characterized by the formation of pearl-necklace clusters followed by their coalescence into a spherical globule—wherein the relaxation dynamics and activation energies exhibit distinct dependencies on confinement radius and temperature, despite a universal power law governing cluster growth at fixed confinement.
This study demonstrates that the cooperative effect of Rashba spin-orbit coupling and Coulomb attraction stabilizes topological spin-triplet excitonic condensates in two-dimensional electron-hole systems, driving a transition from trivial to topological states with a quantized Chern number of and identifying soft spin-up triplet modes as precursors to condensation.
This paper analytically derives the free energy and phase diagram of a spherical Hopfield model with Gaussian-correlated pattern structures, revealing that a spin glass phase emerges at high temperatures while a glass phase containing both patterns and correlations appears at lower temperatures under low loading capacity.
This study demonstrates that the parameter-free Random Barrier Model outperforms the von Schweidler law in fitting the inherent dynamics of a viscous ternary Lennard-Jones liquid and accurately predicting its diffusion coefficient, despite the model's unrealistic assumption of identical energy minima.
This Perspectives article argues that predictive, first-principles simulations spanning materials to architectures are essential for co-designing specialized hardware capable of achieving orders-of-magnitude improvements in the energy efficiency of next-generation AI systems.
This study reports that the triangular quantum antiferromagnet ErMgGaO exhibits a spin glass transition and a low-energy dynamic magnetic continuum that, when analyzed via inelastic neutron scattering and linear spin wave theory, places the material near the theoretical phase boundary between stripy and 120 ordered states, suggesting a proximate quantum spin liquid ground state.
This paper provides a rigorous theoretical justification for the noise-cancellation algorithm in interacting Brownian systems by proving that cross-correlations vanish in thermal equilibrium—rendering the method exact—while demonstrating that finite cross-correlations in nonequilibrium systems serve as a distinct fingerprint of non-equilibrium physics requiring specific corrections.
This paper demonstrates that the stability of flat-band superfluidity in two-dimensional systems depends critically on the specific distribution of the quantum metric within the Brillouin zone rather than just its integrated value, revealing that at least three bands are required for stable condensation and that the superfluid weight is significantly influenced by the condensate quantum metric.
This paper introduces new hard benchmarks for Constraint Satisfaction Problems derived from statistical physics to demonstrate that, contrary to some claims, classical heuristics currently outperform Graph Neural Networks on truly difficult instances.
This study experimentally demonstrates that the effective friction coefficient of a sphere rolling on a granular slope is governed by a linear relationship with the normalized sinking depth, where the intercept decreases with the slip ratio while the slope remains constant.
This paper derives the exact solution for a two-dimensional Ising model with next-nearest-neighbor interactions at zero magnetic field by adapting 3D Ising methods to analyze transfer matrices in multiple representations, ultimately obtaining the partition function and spontaneous magnetization to demonstrate how increased interactions and topological contributions elevate the critical point.
