A stochastic golden rule and quantum Langevin equation for the low density limit
L. Accardi, A. N. Pechen, I. V. Volovich
A rigorous derivation of quantum Langevin equation from microscopic dynamics in the low density limit is given. We consider a quantum model of a microscopic system (test particle)…

Quantum Multipole Noise and Generalized Quantum Stochastic Equations
A. N. Pechen, I. V. Volovich
A notion of quantum multipole (in particular, dipole) noise is considered. Quantum dipole noise is an analogue of quantum white noise but it acts in a Fock space with indefinite me…
