• Abstract: We consider the problem of model reduction for Markovian quantum systems whose dynamics are described by a time-dependent Lindblad generator -- notably, as arising in the presence of external control. Our approach, which builds upon Krylov operator subspaces and operator-algebraic techniques introduced for time-independent generators, returns a reduced model that reproduces exactly the evolution of observables of interest and is guaranteed to be in Lindblad form.

• Floquet exceptional contours in Lindblad dynamics with time-periodic drive and dissipation [0.0]
  We present Floquet analysis of a prototypical qubit whose drive or dissipator strengths are varied periodically. We find that periodic modulations lead to EP lines at small dissipator strengths, and a rich EP structure in the parameter space. Our results show that extending Lindblad Liouvillians to the Floquet domain is a new, potentially preferred route to accessing exceptional points.
