This paper establishes rigorous bounds demonstrating that the classical simulability of quantum operators via matrix-product operators is determined by the scaling of their local-operator entanglement, where logarithmic growth of Rényi entropies for guarantees efficient approximation while volume-law scaling for precludes it.
This paper resolves open problems regarding anomalous Mpemba-like relaxations in the thermodynamic limit by demonstrating that a continuous spectrum of time scales emerges in the antiferromagnetic Ising model, and by proposing an ansatz linking slow relaxation dynamics to metastable phase susceptibility to predict and validate optimal protocols for various anomalous cooling and heating effects.
This paper establishes an analytical theory and scaling laws demonstrating that entropic forces in tether-mediated nanofilament bundles can paradoxically induce attractive metastable states rather than disaggregation, a phenomenon governed by the ratio of excluded-volume radius to tether length and confirmed by Brownian dynamics simulations.
This paper demonstrates that formulating a well-posed minimum work transition problem in finite-time stochastic thermodynamics requires imposing speed limits on control protocols, a constraint that distinguishes optimal equilibration from minimum work processes and reveals that only generalized Schrödinger bridges remain physically consistent when such limits are removed.
This paper presents the first exact microscopic derivation of the M-Wright function characterizing anomalous integrated spin current fluctuations in a one-dimensional Fermi-Hubbard model with infinitely strong repulsive interactions, thereby extending the understanding of universal transport behaviors from classical to quantum many-body systems.
This paper introduces a nonequilibrium instanton framework to demonstrate that path entropy, rather than thermodynamics, governs the stability of metastable spatial patterns in stochastic reaction-diffusion systems by modulating transition rates between competing phases.
This paper provides the first concise analytical derivation of the Ericson transition in stochastic quantum scattering using the Heidelberg approach, proving the emergence of a universal Gaussian distribution for scattering matrix elements and validating these results through comparison with microwave experiments and numerical simulations.
This paper demonstrates that the spectrum of the sector in Jordanian-deformed string theory remains integrable and solvable via the Baxter framework despite the breaking of highest-weight symmetry by a non-abelian Drinfel'd twist, yielding analytic results that match the deformed string spectrum at the one-loop level.
This paper establishes rigorous integrability conditions for one-dimensional quantum systems to be classified as free or interacting fermions by defining free fermions through the simultaneous satisfaction of the Yang-Baxter equation and Shastry's decorated star-triangle relation, and provides a procedure to construct integrable interacting models, such as the Hubbard and XY models, via deformations of these free fermionic -matrices.
This paper establishes a direct relationship between the non-stabilizing power of generic quantum circuits and their constituent non-Clifford gates, demonstrating how random Clifford operations drive the thermalization of non-stabilizerness to its Haar-averaged value and elucidating its critical role in the emergence of quantum chaos.
This paper investigates a mean-field model of random multiplicative growth with redistribution, revealing that while strong migration prevents total localization under static growth rates, the addition of temporal noise induces a distinct partially localized phase that mitigates but does not eliminate extreme concentration, with implications for understanding population dynamics and wealth inequality.
This study numerically demonstrates how the hidden geometry and spectral dimensions of 5-clique-based simplicial complexes, combined with pairwise and higher-order interactions, shape hysteresis loops and induce local synchronization patterns that impede global synchronization in phase oscillator systems.
This paper presents and experimentally validates an efficient protocol that utilizes classical shadows from local randomized measurements to learn the matrix-product operator representation of large-scale mixed quantum states, successfully demonstrated on a superconducting processor with up to 96 qubits.
This paper establishes a unified formalism for the symmetric and antisymmetric components of integrated covariances in nonequilibrium steady states, expressing them via excess observables and deriving thermodynamic bounds that link antisymmetric fluctuations and self-averaging speedups to entropy production and cycle affinities.
This study combines variational analysis and molecular dynamics simulations to map the ground-state phase diagram of two-dimensional core-softened particles, revealing a rich landscape of cluster lattices, Bravais structures, and frustration-induced quasicrystals driven by competing length scales.
This paper establishes a unified framework linking supersymmetry, Markov dualities, and shape-invariance exact solvability by analyzing the factorized structure of one-dimensional Fokker-Planck generators and their supersymmetric partners, extending these concepts to both diffusion processes and nearest-neighbor Markov jump processes.
This paper challenges the traditional view that macroscopic fluctuations and spontaneous symmetry breaking are incompatible in Bose-Einstein condensation by proposing an alternative framework for the uniform ideal gas where the standard Bogoliubov quasi-average fails, and the observed phenomena are explained through the condensation of fluctuations and long-range correlations.
This paper presents a landscape-agnostic study of rare dynamical events in mean-field disordered systems that reveals a rich diversity of instanton structures beyond classical nucleation theory, thereby identifying the point of irreversibility and clarifying the landscape features governing activated relaxation in the RFOT universality class.
This paper establishes a unified theoretical framework based on spinful quasiperiodic systems that achieves exact solvability for all seven fundamental localization phases, including novel models with mobility edges, and proposes feasible experimental schemes for their realization.
This study demonstrates that introducing competitive cyclic loops within active Potts models allows for the control of spatially coexisting states and pattern formation—ranging from simultaneous spiral waves to stochastic switching and homogeneous cycling—by tuning flip energies and the specific network topology of the state transitions.
