Exciton Transport on a Polaritonic Quantum Wire

Polaritonic materials have been shown to possess enhanced transport properties. This observation is attributed to the strong interaction between light and matter promoted within these materials. Theoretical investigations on these systems traditionally employ a Tavis-Cumming effective picture that attempts to provide a general qualitative view of the phenomena. However, the effect of disorder and a multimode description of light on kinetic properties remains unclear. In this work, we provide extensive numerical simulations of wave packet evolution on polaritonic wires. We investigate the convergence of our results with respect to the size of the system and the number of cavity modes describing the radiation field. Moreover, transport and localization properties are evaluated for a range of parameters including disorder strength, detuning, and effective coupling strength. We discuss the implication of our results for theoretical models as well as the connection to recent experimental findings.
