Approach to ground state and time-independent photon bound for massless spin-boson models
W. De Roeck, A. Kupiainen
It is widely believed that an atom interacting with the electromagnetic field (with total initial energy well-below the ionization threshold) relaxes to its ground state while its…

Diffusion for a quantum particle coupled to phonons in
W. De Roeck, A. Kupiainen
We prove diffusion for a quantum particle coupled to a field of bosons (phonons or photons). The importance of this result lies in the fact that our model is fully Hamiltonian and…
