Thermodynamics for Trajectories of a Mass Point [PDF]

, 2014
On the basis of information theory, a new formalism of classical non-relativistic mechanics of a mass point is proposed. The particle trajectories of a general dynamical system defined on an (1+n)-dimensional smooth manifold are treated geometrically as ...

Heat-exchange statistics in driven open quantum systems

New 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)

Entropy, 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

Analysis of contribution of matrix mechanics on quantum mechanics [PDF]

EPJ Web of Conferences
In this paper the analysis and discussion about the contribution made by matrix mechanics, i.e. the establishment of complex form of quantum mechanics and the proposal of mathematic formalism of uncertainty principle, to the development of quantum ...

Quantum theory: the role of microsystems and macrosystems [PDF]

, 2007
We stress the notion of statistical experiment, which is mandatory for quantum mechanics, and recall Ludwig's foundation of quantum mechanics, which provides the most general framework to deal with statistical experiments giving evidence for particles ...

Prequantum classical statistical model with infinite dimensional phase-space [PDF]

, 2005
We show that quantum mechanics can be represented as an asymptotic projection of statistical mechanics of classical fields. Thus our approach does not contradict to a rather common opinion that quantum mechanics could not be reduced to statistical ...

Subdynamics as a mechanism for objective description [PDF]

, 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.

Aspects of Quantum Statistical Mechanics: Fractional and Tsallis Approaches

Mathematics, 2023
We investigated two different approaches, which can be used to extend the standard quantum statistical mechanics. One is based on fractional calculus, and the other considers the extension of the concept of entropy, i.e., the Tsallis statistics.

Gibbsing spacetime: a group field theory approach to equilibrium in quantum gravity

New Journal of Physics, 2018
The symmetries, subtle nature of observables, and lack of a preferred notion of time evolution all make defining a quantum statistical mechanics of general relativity difficult.

On Quantum Statistical Mechanics: A Study Guide

Advances in Mathematical Physics, 2017
We provide an introduction to a study of applications of noncommutative calculus to quantum statistical physics. Centered on noncommutative calculus, we describe the physical concepts and mathematical structures appearing in the analysis of large quantum
