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…
A master equation approach to option pricing
Daniel Faller, Francesco Petruccione
A master equation approach to the numerical solution of option pricing models is developed. The basic idea of the approach is to consider the Black--Scholes equation as the macrosc…
