The two-sided Bogoliubov inequality in von Neumann algebras conceptualizes the free energy--quantum correlations link
Benedikt M. Reible, Albert Much, Rainer Verch +2
The quantum-mechanical two-sided Bogoliubov inequality provides upper and lower bounds for the free energy required to separate a system of interacting particles into independent s…

Physico-mathematical model of open quantum systems with varying particle number
Benedikt M. Reible, Luigi Delle Site
We derive the effective Hamiltonian for open quantum systems with varying particle number from first principles. Our derivation relies on the general postulates of quantu…
