Renormalization group for open quantum systems using environment temperature as flow parameter
K. Nestmann, M. R. Wegewijs
We present the -flow renormalization group method, which computes the memory kernel for the density-operator evolution of an open quantum system by lowering the physical tempera…

The connection between time-local and time-nonlocal perturbation expansions
K. Nestmann, M. R. Wegewijs
There exist two canonical approaches to describe open quantum systems by a time-evolution equation: the Nakajima-Zwanzig quantum master equation, featuring a time-nonlocal memory k…

Fermionic duality: General symmetry of open systems with strong dissipation and memory
V. Bruch, K. Nestmann, J. Schulenborg +1
We consider the exact time-evolution of a broad class of fermionic open quantum systems with both strong interactions and strong coupling to wide-band reservoirs. We present a nont…
