Rigorous results on approach to thermal equilibrium, entanglement, and nonclassicality of an optical quantum field mode scattering from the elements of a non-equilibrium quantum reservoir
Stephan De Bievre, Marco Merkli, Paul E. Parris
Rigorous derivations of the approach of individual elements of large isolated systems to a state of thermal equilibrium, starting from arbitrary initial states, are exceedingly rar…

Characterizing the geometry of the Kirkwood-Dirac positive states
Christopher Langrenez, David R. M. Arvidsson-Shukur, Stephan De Bièvre
The Kirkwood-Dirac (KD) quasiprobability distribution can describe any quantum state with respect to the eigenbases of two observables and . KD distributions behave similarl…
