Convolutionless Non-Markovian master equations and quantum trajectories: Brownian motion revisited
Walter T. Strunz, Ting Yu
Stochastic Schr{ö}dinger equations for quantum trajectories offer an alternative and sometimes superior approach to the study of open quantum system dynamics. Here we show that rec…
The non-Markovian quantum behavior of open systems: An exact Monte Carlo method employing stochastic product states
Heinz-Peter Breuer
It is shown that the exact dynamics of a composite quantum system can be represented through a pair of product states which evolve according to a Markovian random jump process. Thi…
Exact quantum jump approach to open systems in Bosonic and spin baths
Heinz-Peter Breuer
A general method is developed which enables the exact treatment of the non-Markovian quantum dynamics of open systems through a Monte Carlo simulation technique. The method is base…
Lamb Shift of Laser-Dressed Atomic States
U. D. Jentschura, J. Evers, M. Haas +1
We discuss radiative corrections to an atomic two-level system subject to an intense driving laser field. It is shown that the Lamb shift of the laser-dressed states, which are the…
Simulating quantum Brownian motion with single trapped ions
S. Maniscalco, J. Piilo, F. Intravaia +2
We study the open system dynamics of a harmonic oscillator coupled with an artificially engineered reservoir. We single out the reservoir and system variables governing the passage…
Quantum jumps and entropy production
Heinz-Peter Breuer
The irreversible motion of an open quantum system can be represented through an ensemble of state vectors following a stochastic dynamics with piecewise deterministic paths. It is…
