seminar: Non-Markovian dynamics of a qubit
speaker: Sabrina Maniscalco (University of Turku, Finland)abstract: We investigate the non-Markovian dynamics of a qubit by comparing two generalized master equations with memory. In the case of a thermal bath, we derive the solution of the recently proposed post Markovian master equation A. Shabani and D.A. Lidar, Phys. Rev. A {\bf 71}, 020101(R) (2005) and we study the dynamics for an exponentially decaying memory kernel. We compare the solution of the post-Markovian master equation with the solution of the typical memory kernel master equation. Our results lead to a new physical interpretation of the reservoir correlation function and bring to light the limits of usability of master equations with memory for the system under consideration.
