Representability Conditions by Grassmann Integration
Volker Bach, Hans Konrad Knörr, Edmund Menge
Representability conditions on the one- and two-particle density matrix for fermion systems are formulated by means of Grassmann integrals. A positivity condition for a certain kin…
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…
Fermion Correlation Inequalities derived from G- and P-Conditions
Volker Bach, Hans Konrad Knörr, Edmund Menge
It is shown in this paper that the G-Condition and the P-Condition from representability imply the fermion correlation estimate from [1] which, in turn, is known to yield a nontriv…
