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.

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

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.

On the Use of Classical Statistical Mechanics in the Treatment of Polymer Chain Conformation

, 1976
Two different treatments of the degrees of freedom of bond stretching and bond angle bending in chain polymers by classical statistical mechanics lead to different and nonequivalent expressions of the partition functions.

Statistical mechanics of quantum-classical systems [PDF]

The Journal of Chemical Physics, 2001
The statistical mechanics of systems whose evolution is governed by mixed quantum-classical dynamics is investigated. The algebraic properties of the quantum-classical time evolution of operators and of the density matrix are examined and compared to those of full quantum mechanics.

Approximation Methods in Classical Statistical Mechanics

, 1962
The pair distribution function for a classical fluid in thermal equilibrium is found to be more closely approximated by the Percus and Yevick (Phys.

Classical statistical mechanics of the sine-Gordon and f 4 chains. Static properties

, 1980
We present and discuss the classical statistical mechanics of the dynamic properties associated with a discretized sine-Gordon and ${\ensuremath{\varphi}}^{4}$ system by using the molecular-dynamics technique.

Statistical origin of classical mechanics and quantum mechanics

Physical Review Letters, 1993
The classical action for interacting strings, obtained by generalizing the time-symmetric electrodynamics of Wheeler and Feynman, is exactly additive. The additivity of the string action suggests a connection between the area of the string world sheets and entropy. We find that the action principle of classical mechanics is the condition that the total

The nature of the liquid-vapour interface and other topics in the statistical mechanics of non-uniform, classical fluids

, 1979
Recent theoretical work on the microscopic structure and surface tension of the liquid-vapour interface of simple (argon-like) fluids is critically reviewed.
