Critical dynamics and tree-like spatiotemporal patterns in exciton-polaritoncondensates
We study nonresonantly pumped exciton-polariton system in the vicinity of the
dynamical instability threshold. We find that the system exhibits unique and
rich dynamics, which leads to spatiotemporal pattern formation. The patterns
have a tree-like structure and are reminiscent of structures that appear in a
variety of soft matter systems. Within the approximation of slow and fast time
scales, we show that the polariton model exhibits self-replication point in
analogy to reaction-diffusion systems
