Rilassamento iperbolico come condizione sufficiente di un campo ergodico pienamente coerente

Abstract

In three cases, one originating from a classical model, the second from the time-evolution operator, and the third from photocount statistics, it is shown that an initially excited coherent field which remains coherent in time development relaxes according to a hyperbolic rather than to an exponential law. This has particular relevance for the analysis of biological systems.
