The functional mechanics: evolution of the moments of distribution function and the poincare recurrence theorem

open access: yesVestnik Samarskogo Gosudarstvennogo Tehničeskogo Universiteta. Seriâ: Fiziko-Matematičeskie Nauki, 2011
One of modern approaches to a problem of the coordination of classical mechanics and the statistical physics - the functional mechanics is considered.

Phase Space Cell in Nonextensive Classical Systems

open access: yesEntropy, 2003
: We calculate the phase space volume Ω occupied by a nonextensive system of N classical particles described by an equilibrium (or steady-state, or long-term stationary state of a nonequilibrium system) distribution function, which slightly deviates ...

A symplectic integrator for molecular dynamics on a hypersphere

open access: yesCondensed Matter Physics, 2020
We present a reversible and symplectic algorithm called ROLL, for integrating the equations of motion in molecular dynamics simulations of simple fluids on a hypersphere Sd of arbitrary dimension d. It is derived in the framework of geometric algebra and

The Phase Space Elementary Cell in Classical and Generalized Statistics

open access: yesEntropy, 2013
In the past, the phase-space elementary cell of a non-quantized system was set equal to the third power of the Planck constant; in fact, it is not a necessary assumption. We discuss how the phase space volume, the number of states and the elementary-cell

Setting Boundaries for Statistical Mechanics

open access: yesMolecules, 2022
Statistical mechanics has grown without bounds in space. Statistical mechanics of noninteracting point particles in an unbounded perfect gas is widely used to describe liquids like concentrated salt solutions of life and electrochemical technology ...

Basis of Local Approach in Classical Statistical Mechanics

open access: yesEntropy, 2005
: An ensemble of classical subsystems interacting with surrounding particles has been considered. In general case, a phase volume of the subsystems ensemble was shown to be a function of time.

Thermodynamics of an Empty Box

open access: yesEntropy, 2023
A gas in a box is perhaps the most important model system studied in thermodynamics and statistical mechanics. Usually, studies focus on the gas, whereas the box merely serves as an idealized confinement.

Non-equilibrium statistical physics, transitory epigenetic landscapes, and cell fate decision dynamics

open access: yesMathematical Biosciences and Engineering, 2020
Statistical physics provides a useful perspective for the analysis of many complex systems; it allows us to relate microscopic fluctuations to macroscopic observations.

Rupture et continuité dans la physique française : Henri Poincaré et les fondements mécaniques de la thermodynamique

open access: yesPhilosophia Scientiæ, 2023
After 1850, Laplacian or Amperean molecular physics found itself in competition with other approaches involving thermodynamics and kinetic theories. Henri Poincaré is one of the very few French scientists to have made a significant contribution to the ...

An Introduction to Noncommutative Physics

open access: yesPhysics, 2023
Noncommutativity in physics has a long history, tracing back to classical mechanics. In recent years, many new developments in theoretical physics, and in practical applications rely on different techniques of noncommutative algebras.
