Nonperturbative Resummation of Divergent Time-Local Generators: Disentangling Non-Markovian Dynamics

Dragomir Davidovic

Perturbative van Kampen cumulant expansions of time-local generators of open quantum systems generically diverge at long times, but the reduced dynamics is regular. We show that th…
