'Return to equilibrium' for weakly coupled quantum systems: a simple polymer expansion
W. De Roeck, A. Kupiainen
Recently, several authors studied small quantum systems weakly coupled to free boson or fermion fields at positive temperature. All the approaches we are aware of employ complex de…

Absence of Embedded Mass Shells: Cerenkov Radiation and Quantum Friction
W. De Roeck, J. Froehlich, A. Pizzo
We show that, in a model where a non-relativistic particle is coupled to a quantized relativistic scalar Bose field, the embedded mass shell of the particle dissolves in the contin…
