dc.abstract.enMicrocavity-polaritons in lattice geometries have been used to study a wide range of interesting physics. Meanwhile, organic materials have shown great promise on the road towards polaritonic devices, as the strong binding energy of their Frenkel excitons permits room temperature condensation and lasing. Whilst there are theoretical treatments of the condensation processes in planar organic microcavities, models of lattice geometries are lacking. Here, we introduce a model for describing the dynamics of lattices of zero-dimensional organic microcavities, where the dominant condensation mechanism involves the emission of a vibrational phonon. We also provide an open source software module that can be easily modified for any lattice geometry or dimension. The vibronic transition provides a tool for targeted condensation in a particular eigenmode of the system, which we highlight by examining a dimer and a dimerised chain. For the dimer, we observe a double resonance in the condensation efficiency that arises from tuning the condensate-reservoir detuning into resonance with either the symmetric or antisymmetric mode. This mechanism was also exploited in the dimerised chain, to selectively condense the system in to either the bulk states or the topological edge states, under homogeneous pumping of all cavities. We also showed an interesting signature of chiral transport when pumping a single cavity in the chain, where the direction of propagation depends on the sublattice being pumped.
