Coarse-graining master equation for periodically driven systems


Coarse-graining master equation for periodically driven systems

Hotz, R.; Schaller, G.

We analyze Lindblad-Gorini-Kossakowski-Sudarshan-type generators for selected periodically driven open quantum systems. All these generators can be obtained by temporal coarse-graining procedures, and we compare different coarse-graining schemes. Similar to for undriven systems, we find that a dynamically adapted coarse-graining time, effectively yielding non-Markovian dynamics by interpolating through a series of different but invididually Markovian solutions, yields the best results among the different coarse-graining schemes, albeit at highest computational cost.
