Preserving the Hermiticity of the One-Body Density Matrix for a Non-Interacting Fermi Gas

L. M. Farrell, D. Eaton, P. Chitnelawong +2

The one-body density matrix (ODM) for a zero temperature non-interacting Fermi gas can be approximately obtained in the semiclassical regime through different $\hslash$-expansion tec…
