dc.description.abstractWe study theoretically the ground states of topological defects in a spinor four-component condensate of cold indirect excitons. We analyze possible ground-state solutions for different configurations of vortices and half vortices. We show that if only Rashba or Dresselhaus spin-orbit interaction (SOI) for electrons is present the stable states of topological defects can represent a cylindrically symmetric half vortex or half-vortex-antivortex pairs or a nontrivial pattern with warped vortices. In the presence of both Rashba and Dresselhaus SOI the ground state of a condensate represents a stripe phase and vortex type solutions become unstable.en_US
