Diffusion for a quantum particle coupled to phonons in $d\geq 3$
quantum particle phonons Mathematical Physics
2011/9/20
Abstract: 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 randomness...
Non-Markovian dynamics for a free quantum particle subject to spontaneous collapse in space: general solution and main properties
Non-Markovian dynamics quantum particle subject general solution and main properties
2010/4/8
We analyze the non-Markovian dynamics of a quantum system subject to spontaneous collapse in space. After having proved, under suitable conditions, the separation of the center-of-mass and relative mo...
