This paper presents and validates a generalized algorithm for efficient Monte-Carlo sampling of metastable systems using non-local updates in collective-variable space under underdamped Langevin dynamics, demonstrating substantial performance improvements over previous overdamped approaches and extending the applicability of machine-learning-based samplers to more realistic molecular systems.
This paper analyzes the non-equilibrium dynamics of the Ising model in one and two dimensions using a virtual walk approach associated with spin states and local energy, demonstrating that finite-time scaling of these walks yields critical exponents consistent with known theoretical values and reveals a distinct non-equilibrium region and time-dependent critical point.
This paper experimentally demonstrates the quantitative decomposition of heat dissipation into housekeeping and excess components in a non-equilibrium nanoscale dot with multi-electron states, revealing a direct correlation between these thermal processes and free-energy generation that achieves an efficiency of 0.25 under driven conditions.
This paper employs Monte Carlo simulations of a U(1) lattice gauge system to demonstrate that the thermal phase transition of a superconductor belongs to the XY universality class, exhibiting critical exponents consistent with Bose-Einstein condensation and neutral boson transitions.
This paper derives a non-equilibrium generalized Langevin equation for multi-dimensional observables using the Mori-Zwanzig formalism, revealing a unique instantaneous friction contribution that vanishes only for uncorrelated components, and demonstrates its application to modeling coupled protein folding kinetics in human islet amyloid polypeptide fibril formation.
This paper extends a hard-core-free functional renormalization group method to three-dimensional Lennard-Jones liquids, demonstrating through numerical calculations that it achieves accuracy comparable to modern integral-equation theories while maintaining superior thermodynamic consistency.
This paper extends the theoretical framework for estimating diffusive flux into stochastically gated tubes by deriving an explicit formula that remains accurate for non-narrow geometries and varying diffusivities, overcoming challenges related to complex 3D geometry and multiplicative noise.
This paper introduces a geometric framework based on the -logarithm linearization principle that unifies the density profiles of 1D quantum fluids across interaction regimes—from the ideal Bose gas to the Tonks-Girardeau gas—within a discrete hierarchy and derives a universal sound velocity scaling law linking static geometry to dynamical excitations.
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.
This paper demonstrates that the Transient Time Correlation Function (TTCF) method is a computationally efficient and precise alternative to traditional time-averaging approaches for calculating nonequilibrium transport coefficients in both linear and nonlinear regimes, as validated through case studies of the Lorentz gas and anharmonic oscillator chains.
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.
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 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 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 paper reviews deterministic and stochastic network-level models to explain how Arrhenius-like temperature dependencies in individual biochemical reactions transform into complex emergent system behaviors, such as non-Arrhenius scaling and thermal limits, thereby bridging empirical temperature response curves with the molecular organization of biological systems.
This review article surveys phenomenological and microscopic models used to describe the complex, non-Arrhenius temperature responses of biological systems across various scales, defining key operational metrics like optimal temperatures and thermal limits while setting the stage for a subsequent discussion on how system-level curves emerge from interacting reactions.
Motivated by proton transport in solid oxides, this paper extends the asymmetric simple exclusion process to a one-dimensional backbone with tree-like branches, deriving the exact stationary distribution and analyzing how specific network geometries influence transport properties through hypergeometric series.
This paper establishes a fluctuation-based canonical framework for identifying third-order phase transitions through a cumulant-ratio criterion that links to microcanonical classifications, avoids density-of-states reconstruction, and applies to both equilibrium and nonequilibrium systems.
This paper introduces a method utilizing local data to classify superselection sectors and topological defect lines in two-dimensional conformal field theories, thereby establishing a unified framework for deriving selection rules governing renormalization group flows in coset and parafermion models.
