This paper establishes that dynamical quantum phase transitions (DQPTs) in generic quadratic fermionic systems are fundamentally characterized by the restoration of spin-flip symmetry in specific zero-energy dynamical critical modes, providing a unified framework that explains the necessary but insufficient conditions for DQPTs and their relationship to ground-state quantum phase transitions.
This study uses Monte Carlo simulations to demonstrate that quasi-three-dimensional stick percolation systems, despite having a higher percolation threshold than their two-dimensional counterparts, share the same universal finite-size scaling function as 2D continuum and lattice percolation.
This paper establishes that the extreme value statistics of non-stationary, recurrent systems governed by infinite ergodic theory and an infinite invariant density are determined by the return exponent and the infinite measure, leading to a distinct universality class that deviates from the classical Fréchet, Gumbel, and Weibull distributions.
The paper introduces the "worm decoder," a Markov-Chain Monte-Carlo-based algorithm that achieves optimal decoding for various qLDPC codes by approximating logical error probabilities, offering rigorous efficiency guarantees for typical errors and demonstrating superior performance over existing methods even under depolarizing noise through the use of soft information.
This paper numerically demonstrates that weak measurements on the ground state of a one-dimensional spin system near a deconfined quantum critical point induce an asymmetric restructuring of entanglement across the phase boundary, suggesting the emergence of a weak first-order phase transition in the thermodynamic limit.
This paper investigates a discrete model of a heterogeneous elastic line with random springs, demonstrating that when the spring constant distribution follows a power law with exponent , the system exhibits anomalous scaling driven by sample-to-sample fluctuations and abrupt shape jumps, a finding that challenges previous theoretical predictions and is validated by numerical simulations.
Using lattice gauge theory techniques, this study analyzes the spectral properties of SU(3) gauge theory via overlap Dirac eigenvalues to reveal fractal-like clustering near the chiral crossover and estimate a thermalization time of approximately 1.44 fm/c by linking non-equilibrium chaotic momentum modes to thermal magnetic scales.
This paper analytically and numerically investigates a lattice Lorentz gas on a cylinder, demonstrating how crowding and quasi-confinement induce a dimensional crossover from two to one dimensions in equilibrium and characterizing the resulting stationary velocity and diffusion under an external pulling force to first order in obstacle density.
This paper investigates the one-dimensional stochastic porous medium equation with additive white noise, combining functional renormalization group predictions and extensive numerical simulations to characterize its growth exponents, anomalous scaling, and multiscaling properties, while identifying its stationary measure with a random walk model related to a Bessel process.
This paper investigates a generalized two-species Vicsek model with reciprocal intra- and interspecies alignment couplings, revealing that anti-aligning interactions can surprisingly promote global polar order and novel microphase separation, a mechanism that extends to multi-species systems with cyclic interactions.
This paper establishes a unified framework for classical and quantum speed limits by demonstrating that temporal Fisher information is bounded from above by physical costs (such as entropy production and Hamiltonian variance) and from below by statistical distances, thereby constraining the minimal time required for state transformations.
This paper investigates quantum kinetically constrained models with symmetry to demonstrate how the interplay of constraints and chiral symmetry induces Hilbert space fragmentation and a parametric increase in zero modes, leading to the emergence of robust collective bound states that challenge ergodicity.
This paper demonstrates that the two-dimensional long-range Ising model with a line defect fails to factorize in the infrared limit, a phenomenon attributed to the model's equivalence to a higher-dimensional local conformal field theory where the extra dimension maintains connectivity across the defect.
This paper presents a classical theory derived from first-principles statistical mechanics that incorporates electron-ion correlation effects via image charges to quantitatively explain experimental double-layer capacitance data and unify the phenomena of double-layer charging and ion adsorption.
This paper compares three frameworks for modeling complex fluid flows—local conservation laws, the GENERIC formalism, and the Onsager principle—by illustrating their application to isothermal and incompressible polymeric fluids.
This paper proposes a "field digitization scaling" framework that treats the number of discrete field values as a renormalization group coupling, successfully applying it to relate the 2D classical clock model to the XY model and its quantum gauge theory counterpart to enable continuum limit analysis in quantum simulations.
This paper presents a thermodynamically consistent coarse-graining framework based on Doi-Peliti field theory that maps interacting particles to exact field theories, revealing how Poissonian statistics and noise effects govern distinct phase transition behaviors in low- and high-density regimes of the active Ising model.
This study reveals that defect creation and annihilation in diverse active living systems exhibit spatial symmetry breaking and irreversibility driven by a dualism between nematic structure and polar forces, challenging conventional active nematic theories and highlighting these processes as major sources of entropy production.
This paper revisits the pseudomode formalism for open quantum systems to investigate design subtleties, demonstrating how non-diagonalizable couplings generate unique spectral densities, revealing significant freedom in parameter construction, challenging convergence assumptions for evenly distributed modes, and connecting the concept to scattering theory.
This paper analyzes the spatiotemporal stability of synchronized states in coupled map lattices by performing a linear stability analysis of the orbit Jacobian in reciprocal space to determine how coupling strength influences stability against both periodic and incoherent perturbations.
