Quantifying quantum decoherence of electronic excitations of moleucles in condensed phases

This afternoon I am giving my talk at the conference. Most of it is based on this review article. Main ideas I want to get across are:

-the main source of decoherence of electronic excitations in large molecules is due to the dielectric relaxation of the environment

-this can be quantified in terms of a spectral density, many of which have been determined experimentally from dynamic Stokes shift measurements

-the relevant time scales are 10's to 100's femtoseconds
