A Lindblad-like dynamical equation for general open-system quantum dynamics: Role of correlations

Aalto Quantum Physics Seminar (Nanotalo). Speaker: Dr. Sahar Alipour (MSP, Aalto University, Finland).

In this talk, I will derive a Lindblad-like dynamical equation for a general quantum system without assuming any approximation. I will explicitly show the dependence of the rates and jump operators on the correlation between the system and its environment. As a special case, a Markovian equation will be derived by assuming that the accumulated correlation between the system and the environment is periodically reset to zero. In comparison to the the standard Markovian equation in the Lindblad form, this Markovian equation relies on less assumptions. I will also remark on some thermodynamical implications of the derived Markovianity condition.
