Time dependence of a general class of quantum distribution functions
We derive an explicit analytic expression for the time development of a generalized class of quantum distribution functions, which include as special cases the Wigner, the normal, and the antinormal distributions. We find ...
Phase-space representations of the Bloch equation
We discuss the phase-space representation of the Bloch equation and present analytic expressions for two generalized classes of distribution functions. Series solutions to order of ħ2 are given. We conclude that the Wigner ...
Surface effects on the diamagnetic susceptibility and other properties of a low temperature electron gas
A general formulation is developed for determining the free energy of a Fermi gas contained in an arbitrary smooth external potential barrier and in a weak magnetic field, in the low-temperature limit. The Wigner phase-space ...
On the classical limit of phasespace formulation of quantum mechanics : entropy
The classical limits of phase‐space formulation of quantum mechanics are studied. As a special example, some properties of both quantum mechanical and classical entropies are discussed in detail.
Magnetic susceptibility of a two-dimensional electron gas in the strong magnetic field limit and for non-zero temperatures
Analytic expressions are derived for the magnetic susceptibility and the Fermi energy of a non-interacting two-dimensional electron gas in the strong field limit and for non-zero temperatures. The results at zero temperature ...
Ideal two-dimensional electron gas in a magnetic field and at non-zero temperatures : an alternative approach
A new exact expression is derived for the free energy of an ideal two-dimensional electron gas (2DEG) in a uniform magnetic field and at low, but finite, temperatures. The approach eliminates a 2D-peculiarity that neither ...
