A manifestly Hermitian semiclassical expansion for the one-particle density matrix of a two-dimensional Fermi gas
K. Bencheikh, B. P. van Zyl, K. Berkane
The semiclassical -expansion of the one-particle density matrix for a two-dimensional Fermi gas is calculated within the Wigner transform method of Grammaticos and Voros, or…

Gradient corrections to the kinetic energy density functional of a two-dimensional Fermi gas at finite temperature
Brandon P. van Zyl, K. Berkane, K Bencheikh +1
We examine the leading order semiclassical gradient corrections to the non-interacting kinetic energy density functional of a two dimensional Fermi gas by applying the extended Tho…
