Description

The growing field of polariton chemistry calls for a deeper understanding of the role the different vibrational modes play in the system. The ability of low frequency vibrational modes to act as a reservoir of energy to facilitate off-resonant transitions is likely to be relevant in many processes. However, the non-Markovian nature of those modes make them hard to model. One way to capture these effects is using process tensor matrix product operator methods to describe the vibrational environment of the molecules while describing the light using mean-field approximations.
In this talk I will demonstrate the use of this approach to model the energy transfer between different species of molecules that couple to the same cavity photon mode. To do this we look at how the emission spectra of the combined system evolves over time, and how this is affected by the coupling to a continuum of vibrational modes.
