Extended Weak Coupling Limit for Pauli-Fierz Operators
Jan Derezinski, Wojciech De Roeck
We consider the weak coupling limit for a quantum system consisting of a small subsystem and reservoirs. It is known rigorously since [Dav74] that the Heisenberg evolution restrict…

Extended Weak Coupling Limit for Friedrichs Hamiltonians
Jan Derezinski, Wojciech De Roeck
We study a class of self-adjoint operators defined on the direct sum of two Hilbert spaces: a finite dimensional one called sometimes a ``small subsystem'' and an infinite dimensio…
