This paper develops a non-extensive thermodynamic formalism for one-sided shifts by introducing -entropy and -pressure concepts, proving the existence and uniqueness of -equilibrium states for Lipschitz potentials, and establishing connections between these generalized structures and classical Ruelle transfer operators.
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 conjectures a lower bound for the critical exponent in continuous phase transitions described by Landau-Ginzburg-Wilson theories, proposing the inequality (which implies for unitary theories) based on the condition , a hypothesis supported by arguments from lattice models, -expansions, and exact two-dimensional conformal field theory results.
This paper introduces a generalized matrix product operator framework to establish global duality transformations between distinct one-dimensional boundary-driven Markov processes, demonstrating that the symmetric simple exclusion process with out-of-equilibrium boundaries is exactly dual to an equilibrium system where the Gibbs-Boltzmann measure effectively captures non-equilibrium physics.
This paper investigates the weak-coupling limit of the lattice nonlinear Schrödinger integral equation by employing matched asymptotic expansions to derive the ground-state energy and density, revealing a logarithmic divergence linked to the Bose-Einstein distribution and uncovering a resurgent transseries structure through Wiener-Hopf analysis.
This paper verifies that persistent observers in causally invariant hypergraph substrates satisfy the Conant-Ashby Good Regulator Theorem, thereby necessitating internal models that lead to natural gradient descent as the unique learning rule and yielding a model-dependent closed-form formula for Vanchurin's regime parameter with a quantum-classical threshold at .
This paper presents a unified exact solution to the relativistic Boltzmann equation for a boost-invariant conformal gas on across all constant-curvature slicings, which reproduces known Bjorken and Gubser flows while introducing a novel analytic "Grozdanov flow" for hyperbolic foliations that naturally encompasses both hydrodynamic and free-streaming regimes.
This paper benchmarks various parallelization strategies for flat-histogram Monte Carlo sampling and demonstrates that non-uniform energy domain decomposition offers the most significant performance improvements, providing concrete recommendations for optimizing simulations of complex alloy systems.
This paper presents a rigorous formulation of the downfolding procedure to derive exact effective models for arbitrary target spaces by integrating out high-energy degrees of freedom, establishes conditions for perturbative truncation, formally derives the constrained random phase approximation (cRPA) with identified corrections, and validates the approach using material examples like fcc Nickel and SrCuO.
This paper improves finite-time thermodynamic uncertainty relations by incorporating the probability of null-entropy events, thereby deriving tighter bounds on thermodynamic current fluctuations, a framework validated using a qudit SWAP engine.
Using time-dependent spin-wave theory, this paper elucidates the mechanism behind the quantum Mpemba effect in long-range spin systems, demonstrating that quantum fluctuations of magnetization drive the faster restoration of spin-rotational symmetry from larger initial tilt angles across a wide parameter range, a phenomenon absent in some short-range counterparts.
This paper introduces the "time glass," a novel phase of matter in periodically driven dissipative quantum systems characterized by spatial long-range order and synchronized chaotic oscillations that persist indefinitely due to system-size-dependent quantum effects, despite the presence of a finite spectral gap in the thermodynamic limit.
This paper presents the first exact analytic expression for the coherent information of a decohered toric code, rigorously establishing a direct connection between the fundamental error threshold and the criticality of the random bond Ising model without relying on the replica trick.
This paper analytically computes the capacity of entanglement in the Russo-Susskind-Thorlacius (RST) model of two-dimensional dilaton gravity, revealing that while single-interval capacity remains time-independent, the global replica backreaction induces a time-dependent capacity for two intervals that signals non-uniform saddle competition and sharp features at the Page transition.
This paper experimentally demonstrates that the universal Family-Vicsek scaling laws, originally established for classical surface growth, also govern the non-equilibrium dynamics of quantum fluctuations in a one-dimensional Bose gas, thereby unifying the understanding of universality across classical and quantum systems.
This paper demonstrates that the Rényi tripartite information in free-fermion systems exhibits a unique, -dependent scaling landscape where integer Rényi indices suffer from a "replica obstruction" that prevents reconstruction of the leading von Neumann signal, whereas negativity-based measures offer a significantly enhanced signal compared to standard entropy.
This paper proposes and validates a method for studying scaling dimensions of three-dimensional conformal field theories using near-term quantum simulators, demonstrating high accuracy with as few as 20 qubits on the Ising model to solve a problem that is currently difficult for classical computers.
This paper demonstrates that numerically optimized time-dependent driving can overcome the fidelity limitations of qubit reset caused by polaron formation beyond the Born-Markov approximation by actively steering system-environment correlations, even in realistic multilevel transmon systems with filtered environments.
This paper demonstrates that by actively controlling the time-dependent coupling between a transmon qubit and its dissipative environment to reverse detrimental polaron formation, it is possible to achieve rapid, high-fidelity qubit reset in non-Markovian systems.
This paper investigates the topological phase transitions of a deformed toric code by mapping its wavefunction norm to classical partition functions, revealing a rich phase diagram with three distinct phases separated by critical lines characterized by and parafermion conformal field theories, as well as isolated critical points exhibiting Hilbert space fragmentation and quantum many-body scars.
