Correlation-Dependent Coherent to Incoherent Transitions in Resonant Energy Transfer Dynamics
Correlation-Dependent Coherent to Incoherent Transitions in Resonant Energy Transfer Dynamics
I investigate energy transfer in a donor-acceptor pair beyond weak system-bath coupling. I identify a transition from coherent to incoherent dynamics with increasing temperature, due to multiphonon effects not captured by a standard weak-coupling treatment. The crossover temperature has a marked dependence on the degree of spatial correlation between fluctuations …
