SEMINAR: Dr. Etienne Wamba

You are cordially invited to the SCL seminar of the Center for the Study of Complex Systems, which will be held on Thursday, 29 March 2018 at 14:00 in the library reading room “Dr. Dragan Popović” of the Institute of Physics Belgrade. The talk entitled

N-point functions mapping for dissipative quantum systems

will be given by Dr. Etienne Wamba (Humboldt Fellow, Department of Physics, Technical University of Kaiserslautern, Germany).

Abstract of the talk:

Motivated by recent experimental efforts for achieving and controlling dissipative quantum systems, in this talk we will consider a D-dimensional quantum gas that interacts with a bath and evolves according to a Lindblad master equation. Invoking the picture independence of expectation values and using the quantum fields that describe the gas dynamics, we will derive the Heisenberg evolution of any arbitrary N-point function of the system in the regime when the Lindblad generators feature a loss or gain. Our quantum field mapping [1] for closed quantum systems will be extended to open quantum systems by relating onto each other two different evolutions of the N-point functions of the dissipative quantum system.
