Ideal Quantum Gases
The indistinguishability of identical particles has profound effects at low temperatures and/or high density where quantum mechanical wave packets overlap appreciably. The occupation representation is used to study the statistical mechanics and thermodynamics of ideal quantum gases satisfying FermiDirac or Bose-Einstein statistics. This notebook concentrates on formal and conceptual development...
متن کاملOn Classical Ideal Gases
We show that the thermodynamics of ideal gases may be derived solely from the Democritean concept of corpuscles moving in vacuum plus a principle of simplicity, namely that these laws are independent of the laws of motion, aside from the law of energy conservation. Only a single corpuscle in contact with a heat bath submitted to a z and t-invariant force is considered. Most of the end results a...
متن کاملFermi gases in harmonic oscillator potential traps
We study the thermodynamic properties of an ideal gas of fermions in a harmonic oscillator confining potential. The analogy between this problem and the de Haasvan Alphen effect is discussed and used to obtain analytical results for the chemical potential and specific heat in the case of both isotropic and anisotropic potentials. Step-like behaviour in the chemical potential, first noted in num...
متن کاملUniqueness of chemical equilibria in ideal mixtures of ideal gases
We prove the uniqueness of chemical equilibrium for an ideal mixture of ideal gases in a closed, spatially homogeneous volume. Uniqueness, a fundamental issue of chemical physics, is incompletely justified in textbooks and much of the scientific literature. We first reproduce a little known proof by Zel’dovich and show in a more direct fashion than originally presented that a unique equilibrium...
متن کاملTRAPS - A Time Dependent Resource Allocation Language
A general language for specifying resource allocation in Scheduling problems is presented. TRAPS is a superclass of the RAPS (Resource Allocation Problem Specication) language developed by the authors [31]. TRAPS enables the speci cation of a scheduling problem by adding built in time operators, on top of existing terms for resources, activities, allocation rules and constraints. In this way TR...
