Non-adiabatic effects in periodically driven-dissipative open quantum systems
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 periodic modulation of its parameters. Using Floquet's
theorem, we formulate the differential equation for the system's density
operator which has to be solved for a single period of modulation. On this
basis we also provide systematic expansions in both the adiabatic and
high-frequency regime. Applying our method to three different systems -- two-
and three-level models as well as the driven nonlinear cavity -- we propose
periodic modulation protocols of parameters leading to a temporary suppression
of effective dissipation rates, and study the arising non-adiabatic features in
the response of these systems.Comment: 12 pages, 8 figure
