Constraints for relaxation rates for open quantum systems
Seminar recording on Youtube
Relaxation rates provide important characteristics both for classical and quantum processes. Essentially they control how fast the system thermalizes, equilibrates, decohere, and/or dissipate. Moreover, very often they are directly accessible to be measured in the laboratory and hence they define key physical characteristics of the system. In my talk I show that relaxation rates for any Markovian evolution of an open system satisfy a universal tight constraint (valid for all quantum systems with finite number of energy levels). Some implications of this result are discussed as well.
