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…

Density-operator evolution: Complete positivity and the Keldysh real-time expansion
V. Reimer, M. R. Wegewijs
We study the reduced time-evolution of open quantum systems by combining quantum-information and statistical field theory. Inspired by prior work [EPL 102, 60001 (2013) and Phys. R…

Non-adiabatic effects in periodically driven-dissipative open quantum systems
Viktor Reimer, Kim G. L. Pedersen, Niklas Tanger +2
We present a general method to calculate the quasi-stationary state of a driven-dissipative system coupled to a transmission line (and more generally, to a reservoir) under periodi…
