Quantization of the classical bistable-potential Mpemba effect shifts anomalous relaxation to ultra-cold temperatures and produces inverse and double-inverse Mpemba effects absent in classical dynamics.
Ultimate precision bounds for multiparameter Markovian noise metrology show average variance scaling as Ω(1/(T R²)) with Heisenberg scaling in dissipative channels R when using entangled probes and high-rank signal correlations, attainable via rapid prepare-and-measure protocols.
In a minimal non-reciprocal graphene model, quantum capacitance scales as (1 - β²)^{-1} near the exceptional point, offering an equilibrium thermodynamic signature of non-Hermiticity.
A nonperturbative bound on evolution distance yields explicit upper bounds on errors of the rotating-wave and secular approximations in dissipative open quantum systems.
The convergence crop-length of the polar-decomposition topological invariant in finite non-Hermitian chains is shown to be governed by skin-effect decay lengths, and is predicted by random-forest regression using root-derived features.
Derives a projected quantum speed limit via quantum Fisher information on a quotient manifold to profile out calibration nuisance parameters for Markovian dynamics, with explicit application to Jaynes-Cummings sensors.
Pseudomode elimination works for nonlinearly intercoupled modes in cQED whenever the eliminated sector's self-energy on the retained subsystem is rational, enabling finite damped auxiliaries independent of retained nonlinearities.
An intrinsic reference basis yields a cohesion index that contracts exponentially under aligned dephasing, giving operational classicality and candidate pointer sectors.
Time evolution of genuine multipartite negativity in the open Kitaev quantum spin liquid shows persistence in loopy subregions in Markovian regime and at higher temperatures in non-Markovian regime.
Derives Lindblad master equation for spacetime-noise decoherence with Gamma proportional to E^{-4} and applies it to damped neutrino flavor oscillations.
Modulating relative weights of interaction channels in a quantum Brownian motion model allows control over non-Markovianity, inducing transitions to Markovian regimes using Gaussian master equations.
Physics-informed quantum neural networks trained on noisy measurements can construct nontrivial decision boundaries to classify quantum states via order parameters and are suited for NISQ hardware due to links with Markovian open many-body systems.
Language generation requires dissipative quantum dynamics with non-local aggregation, not conservation laws, framing it as dissipative quantum field theory.
Local quantum memory criteria applied via matrix product operator methods show that single-intervention process tensors generally predict quantum memory at low temperatures in spin-boson models, while dynamical maps detect it for resonant environments at short times.
In Markovian open quantum systems with bistability, noise-induced stochastic switching limits relaxation and follows an Arrhenius law with inverse system size as effective temperature, distinct from deterministic slow relaxation due to a small Liouvillian gap.
