Spin and statistics in classical mechanics [PDF]
American Journal of Physics, 2004 The spin–statistics connection is obtained for classical particles. The connection holds within pseudomechanics, a theory of particle motion that extends classical physics to include anticommuting Grassmann variables, and that exhibits classical analogs of both spin and statistics.

Setting Boundaries for Statistical Mechanics
Molecules, 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 ...

Thermodynamics of an Empty Box
Entropy, 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.

Philosophia 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 ...

The classical–statistical limit of quantum mechanics [PDF]
Physica A: Statistical Mechanics and its Applications, 2004 The classical-statistical limit of quantum mechanics is studied. It is proved that the limit $\hbar \to 0$ is the good limit for the operators algebra but it si not so for the state compact set. In the last case decoherence must be invoked to obtain the classical-statistical limit.

An Introduction to Noncommutative Physics
Physics, 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.

Classical statistical mechanics of constraints: a theorem and application to polymers.
Proceedings of the National Academy of Sciences of the United States of America, 1974 A classical system of mass points subject to holonomic constraints has a kinetic energy dependent on the coordinates as well as the moments of the remaining degrees of freedom.

Entropy, 2018 The Gibbs Paradox is essentially a set of open questions as to how sameness of gases or fluids (or masses, more generally) are to be treated in thermodynamics and statistical mechanics.
