Coarse-graining master equation for periodically driven systems

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. Similarly to undriven systems, we find that a dynamically adapted coarsegraining time, effectively yielding non-Markovian dynamics by interpolating through a series of different but individually Markovian solutions, gives the best results among the different coarse-graining schemes, albeit at the highest computational cost.

Automated summary

For selected periodically driven open quantum systems, dynamically adapted coarse-graining time yields the best results among different coarse-graining schemes, at a high computational cost. This non-Markovian dynamics interpolates through a series of individually Markovian solutions.
