| contents | Light-induced nonadiabatic effects can arise from the interaction of a molecule with the quantized electromagnetic field of a Fabry--Pérot or plasmonic nanocavity. In this context, the quantized radiation field mixes the vibrational, rotational, and electronic degrees of freedom. In this work, we investigate the photodissociation dynamics of a rotating hydrogen molecule within a lossy plasmonic nanocavity. We highlight that, due to significant cavity loss, the dynamics are governed by an infinite number of light-induced conical intersections. We also examine the dissociation dynamics of fixed-in-space molecules by neglecting rotation, employing both the Lindblad master and non-Hermitian lossy Schrödinger equations. Additionally, we incorporate the effects of rotation within the parameter range of perfect agreement using the non-Hermitian lossy Schrödinger method. Furthermore, we show that in the absence of photon losses, there is a close correspondence between the classical Floquet description and the radiation field model. |
