Quantum resonance theory of open system dynamics Merkli, Marco


We present a mathematical method allowing to prove the validity of the Markovian approximation for an $N$-level quantum system in contact with thermal reservoirs. The true system dynamics is approximated by a completely positive, trace preserving dynamical group $f\!or\ all\ times\ t\ge0$, provided the system-reservoir coupling $\lambda$ is small but fixed. No weak coupling condition $\lambda^2 t\lesssim {\rm const.}$ is imposed.
