Polariton gap and gap-stripe solitons in Zeeman lattices

Abstract

We predict that spatially modulated Zeeman splitting resulting in the formation of Zeeman lattice can be used for creation of localized self-sustained excitations in spinor polariton condensates with dominant repulsive interactions. In such lattices, the phenomenon of TE-TM splitting, playing the role of effective spin-orbit interaction, leads to the emergence of the stripe phase and formation of stable gap-stripe solitons with complex intrinsic structure resulting from the presence of two characteristic spatial scales, one of which is set by the period of Zeeman lattice, while other is set by the momentum in the depth of the Brillouin zone, at which such solitons bifurcate from the linear spectrum. Gap-stripe polariton solitons can be excited by suitable resonant pump.
