Quantum Mechanics: Statistical Balance Prompts Caution in Assessing Conceptual Implications

open access: yesEntropy, 2022
Throughout quantum mechanics there is statistical balance, in the collective response of an ensemble of systems to differing measurement types. Statistical balance is a core feature of quantum mechanics, underlying quantum mechanical states, and not yet ...

Equilibration, thermalisation, and the emergence of statistical mechanics in closed quantum systems [PDF]

open access: yesReports on progress in physics. Physical Society, 2015
We review selected advances in the theoretical understanding of complex quantum many-body systems with regard to emergent notions of quantum statistical mechanics.

Quantum statistical mechanics of vortices

open access: yesJournal of Physics A: Mathematical and Theoretical, 2022
Abstract The asymptotic partition function for quantized abelian Higgs vortices at high temperature T is found to leading and subleading order, and from this the equation of state of the vortex gas is derived, including the first quantum correction.

From quantum chaos and eigenstate thermalization to statistical mechanics and thermodynamics [PDF]

open access: yes, 2015
This review gives a pedagogical introduction to the eigenstate thermalization hypothesis (ETH), its basis, and its implications to statistical mechanics and thermodynamics. In the first part, ETH is introduced as a natural extension of ideas from quantum

Entropy of Quantum States

open access: yesEntropy, 2021
Given the algebra of observables of a quantum system subject to selection rules, a state can be represented by different density matrices. As a result, different von Neumann entropies can be associated with the same state.

Test of quantum gravity in statistical mechanics [PDF]

open access: yesPhysical Review D, 2021
We study Quantum Gravity effects on the density of states in statistical mechanics and its implications for the critical temperature of a Bose Einstein Condensate and fraction of bosons in its ground state. We also study the effects of compact extra dimensions on the critical temperature and the fraction.

Heat-exchange statistics in driven open quantum systems

open access: yesNew Journal of Physics, 2014
As the dimensions of physical systems approach the nanoscale, the laws of thermodynamics must be reconsidered due to the increased importance of fluctuations and quantum effects.

Probability, Entropy, and Gibbs’ Paradox(es)

open access: yesEntropy, 2018
Two distinct puzzles, which are both known as Gibbs’ paradox, have interested physicists since they were first identified in the 1870s. They each have significance for the foundations of statistical mechanics and have led to lively discussions with

Subdynamics as a mechanism for objective description [PDF]

open access: yes, 1999
The relationship between microsystems and macrosystems is considered in the context of quantum field formulation of statistical mechanics: it is argued that problems on foundations of quantum mechanics can be solved relying on this relationship.

Colloquium : Statistical mechanics and thermodynamics at strong coupling: Quantum and classical [PDF]

open access: yes, 2019
The question of how classical systems approach thermal equilibrium is as old as the foundations of thermodynamics and statistical mechanics. How quantum systems decohere and thermalize is even more puzzling. This Colloquium provides an account of how the
