Absztrakt:
Molecular cavity quantum electrodynamics examines how confined radiation 
modes - in a Fabry-Perot or plasmonic nano-cavity - interact with molecules. 
The coupling between photons and molecules gives rise to mixed light-matter 
hybrid states, known as polaritons, which exhibit both photonic and molecular 
characteristics. The use of cavities to impact molecular structure and 
dynamics has become popular.
As cavities, in particular plasmonic nanocavities, are lossy and the lifetime 
of their modes can be very short, their lossy nature must be incorporated 
into the calculations. The non-Hermitian Schrödinger and Lindblad master 
equations are commonly considered as appropriate tools to describe this lossy 
nature [1].
The present talk reviews our recent achievements in this area:
i) We demonstrate how the interplay of the atomic, molecular, and photonic 
populations gives rise to rich dynamics in the cavity [2];
ii) We discuss the light-induced nonadiabatic dissociation dynamics of a 
single molecule interacting with a lossy plasmonic nanocavity under strong 
coupling conditions [3,4];
iii) We also investigate the role of nuclear spin statistics and the Pauli 
principle in polaritonic chemistry. We assume vibrational strong coupling and 
study effects associated with the exchange of identical particles for one and 
two molecules coupled to a cavity mode. Our results highlight striking 
quantum-dynamical consequences of the Pauli principle [5].
