Classical Statistical Mechanics

1993
Matter on the macroscopic scale always consists of a very large number of particles (atoms or molecules). The number of particles in the macroscopic volume element of a cubic meter or a liter is of the order of magnitude of 1023. It is self-evident that it makes no sense to try to write out and solve the equations of motion for this number of particles.

Classical Statistical Mechanics

2021
This chapter focusses mainly upon the classical mechanical evaluation of the partition function for a gas of structureless atoms, and begins with a discussion of energy equipartition. The role of interatomic interactions is examined using the grand partition function, as it enables a more convenient separation of the roles played by kinetic and ...

States of Classical Statistical Mechanics

Journal of Mathematical Physics, 1967
A state of an infinite system in classical statistical mechanics is usually described by its correlation functions. We discuss here other descriptions in particular: as (1) a state on a B* algebra; (2) a collection of density distributions; (3) a field theory; (4) a measure on a ``space of configurations of infinitely many particles.'' We consider the ...

Measurement in quantum mechanics and classical statistical mechanics

Physics Letters A, 1992
Abstract It is shown that the uncertainties (ΔP)2 and (ΔQ)2 in momentum and positiion of a quantum particle can always be expressed as the sum of a classical term and a quantum term. For quantum states characterized by a product ΔPΔQ〉h it is always possible to reduce the uncertainty in both P and Q by performing measurements of both of them with ...

Classical Statistical Mechanics

1981
Statistical mechanics is the bridge between molecular science and continuum mechanics. The input to statistical mechanics is a force law between particles. The particles can be atoms in a crystal, molecules in a gas or liquid, electrons in a plasma, amino acid units in a protein, elementary constituents in a complex polymer, etc.
