On the quantum description of Einstein's Brownian motion

Francesco Petruccione, Bassano Vacchini

A fully quantum treatment of Einstein's Brownian motion is given, showing in particular the role played by the two original requirements of translational invariance and connection…

Initial correlations effects on decoherence at zero temperature

B. Bellomo, G. Compagno, F. Petruccione

We consider a free charged particle interacting with an electromagnetic bath at zero temperature. The dipole approximation is used to treat the bath wavelengths larger than the wid…

Non-Markovian dynamics in a spin star system: Exact solution and approximation techniques

Heinz-Peter Breuer, Daniel Burgarth, Francesco Petruccione

The reduced dynamics of a central spin coupled to a bath of N spin-1/2 particles arranged in a spin star configuration is investigated. The exact time evolution of the reduced dens…

Radiation damping and decoherence in quantum electrodynamics

Heinz-Peter Breuer, Francesco Petruccione

The processes of radiation damping and decoherence in Quantum Electrodynamics are studied from an open system's point of view. Employing functional techniques of field theory, the…

Time-local master equations: influence functional and cumulant expansion

Heinz-Peter Breuer, Andrea Ma, Francesco Petruccione

The non-Markovian behaviour of open quantum systems interacting with a reservoir can often be described in terms of a time-local master equation involving a time-dependent generato…

Stochastic wave function approach to generalized master equations

H. P. Breuer, B. Kappler, F. Petruccione

A generalization of the stochastic wave function method is presented which allows the unravelling of arbitrary linear quantum master equations which are not necessarily in Lindblad…
