Generalized One-Particle Density Matrices and Quasifree States
Volker Bach, Sébastien Breteaux, Hans Konrad Knörr +1
In the spirit of the generalized one-particle density matrix for fermions, we introduce generalized one- and two-particle density matrices to state representability conditions up t…

Minimization of the Energy of the Non-Relativistic One-Electron Pauli-Fierz Model over Quasifree States
Volker Bach, Sébastien Breteaux, Timmy Tzaneteas
In this article is proved the existence and uniqueness of a minimizer of the energy for the non-relativistic one electron Pauli-Fierz model, within the class of pure quasifree stat…
