Natural Nonequilibrium States in Quantum Statistical Mechanics [PDF]
Journal of Statistical Physics, 2000 A quantum spin system is discussed, where a heat flow between infinite reservoirs takes place in a finite region. A time dependent force may also be acting. Our analysis is based on a simple technical assumption concerning the time evolution of infinite quantum spin systems.

Extracting rates and activation free energies of martensitic transitions using nanomechanical force statistics: theory, models, and analysis [PDF]
Scientific ReportsNanomechanical responses (force-time profiles) of crystal lattices under deformation exhibit random critical jumps, reflecting the underlying structural transition processes.

Relaxation of Multitime Statistics in Quantum Systems [PDF]
Quantum, 2023 Equilibrium statistical mechanics provides powerful tools to understand physics at the macroscale. Yet, the question remains how this can be justified based on a microscopic quantum description. Here, we extend the ideas of pure state quantum statistical

Exceptional dynamical quantum phase transitions in periodically driven systems
Nature Communications, 2021 Understanding phase transitions in systems out of equilibrium is a topic of high interest. Here the author discusses the spontaneous antiunitary symmetry breaking leading to exceptional dynamical quantum phase transitions in driven many-body systems.

Some speculations about local thermalization of nonequilibrium extended quantum systems
Condensed Matter Physics, 2023 We discuss the possibility of defining an emergent local temperature in extended quantum many-body systems evolving out of equilibrium. For the most simple case of free-fermionic systems, we give an explicit formula for the effective temperature in the ...

Foundations of Nonequilibrium Statistical Mechanics in Extended State Space
Foundations, 2023 The review provides a pedagogical but comprehensive introduction to the foundations of a recently proposed statistical mechanics (μNEQT) of a stable nonequilibrium thermodynamic body, which may be either isolated or interacting. It is an extension of the

Nonequilibrium statistical mechanics of crystals [PDF]
Journal of Statistical Mechanics: Theory and Experiment, 2021 Abstract The local equilibrium approach previously developed by the authors (J Mabillard and P Gaspard 2020 J. Stat. Mech. 103203) for matter with broken symmetries is applied to crystalline solids. The macroscopic hydrodynamics of crystals and their local thermodynamic and transport properties are deduced from the microscopic ...
