Incoherent charge transport in an organic polariton condensate
M. Ahsan Zeb, Peter G. Kirton, Jonathan Keeling
We study how polariton condensation modifies charge transport in organic materials. In typical organic materials, charge transport proceeds via incoherent hopping. We therefore pro…
Organic polariton lasing and the weak- to strong-coupling crossover
Artem Strashko, Peter Kirton, Jonathan Keeling
Following experimental realizations of room temperature polariton lasing with organic molecules, we present a microscopic model that allows us to explore the crossover from weak to…
Superradiant and Lasing States in Driven-Dissipative Dicke Models
Peter Kirton, Jonathan Keeling
We present the non-equilibrium phase diagram of a model which can demonstrate both Dicke--Hepp--Lieb superradiance and regular lasing by varying the coherent and incoherent driving…
Suppressing and restoring the Dicke superradiance transition by dephasing and decay
Peter Kirton, Jonathan Keeling
We show that dephasing of individual atoms destroys the superradiance transition of the Dicke model, but that adding individual decay toward the spin down state can restore this tr…
Spatial dynamics, thermalization, and gain clamping in a photon condensate
Jonathan Keeling, Peter Kirton
We study theoretically the effects of pump-spot size and location on photon condensates. By exploring the inhomogeneous molecular excitation fraction, we make clear the relation be…
Thermalization and breakdown of thermalization in photon condensates
Peter Kirton, Jonathan Keeling
We examine in detail the mechanisms behind thermalization and Bose-Einstein condensation of a gas of photons in a dye-filled microcavity. We derive a microscopic quantum model, bas…
