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…
Time-convolutionless master equation: Perturbative expansions to arbitrary order and application to quantum dots
Konstantin Nestmann, Carsten Timm
The time-convolutionless quantum master equation is an exact description of the nonequilibrium dynamics of open quantum systems, with the advantage of being local in time. We deriv…
Five approaches to exact open-system dynamics: Complete positivity, divisibility and time-dependent observables
Viktor Reimer, Maarten Rolf Wegewijs, Konstantin Nestmann +1
To extend the classical concept of Markovianity to an open quantum system, different notions of the divisibility of its dynamics have been introduced. Here we analyze this issue by…
