Self-localization of polariton condensates in periodic potentials
arXiv:1302.1724 · doi:10.1103/PhysRevLett.110.170407
Abstract
We predict the existence of novel spatially localized states of exciton-polariton Bose-Einstein condensates in semiconductor microcavities with fabricated periodic in-plane potentials. Our theory shows that, under the condition of continuous off-resonant pumping and losses associated with polariton decay, localization is observed for a wide range of optical pump parameters due to effective potentials self-induced by the polariton flows in the spatially periodic system. We reveal that the self-localization of exciton-polaritons in the lattice may occur both in the gaps and bands of the single-particle linear spectrum, and is dominated by the effects of gain and dissipation rather than the applied potential, in sharp contrast to the conservative condensates of ultracold alkali atoms.
