On the generators of quantum dynamical semigroups with invariant subalgebras
Markus Hasenöhrl, Matthias C. Caro
The problem of characterizing GKLS-generators and CP-maps with an invariant appeared in different guises in the literature. We prove two unifying results which hold even for weakly…

Quantum and classical dynamical semigroups of superchannels and semicausal channels
Markus Hasenöhrl, Matthias C. Caro
Quantum devices are subject to natural decay. We propose to study these decay processes as the Markovian evolution of quantum channels, which leads us to dynamical semigroups of su…

Moment-Preserving and Mesh-Adaptive Reweighting Method for Rare-Event Sampling in Monte-Carlo Algorithms
C. U. Schuster, T. Johnson, G. Papp +4
We present novel roulette schemes for rare-event sampling that are both structure-preserving and unbiased. The boundaries where Monte Carlo markers are split and deleted are placed…
