Quantum speed limit for non-Markovian dynamics
We derive a Margolus-Levitin-type bound on the minimal evolution time of an arbitrarily
driven open quantum system. We express this quantum speed limit time in terms of the …

Quantum channels and memory effects
Any physical process can be represented as a quantum channel map** an initial state to a
final state. Hence it can be characterized from the point of view of communication theory, ie …

Coupling of molecular emitters and plasmonic cavities beyond the point-dipole approximation
As the size of a molecular emitter becomes comparable to the dimensions of a nearby
optical resonator, the standard approach that considers the emitter to be a point-like dipole …
