Comment on "Topological stability of the half-vortices in spinor exciton-polariton condensates"
arXiv:1002.1739 · doi:10.1103/PhysRevB.82.127301
Abstract
We show that recent paper by Flayac et al. [Phys. Rev. B 81, 045318 (2010) and arXiv:0911.1650] is misleading. We demonstrate the existence of static half-quantum vortices in exciton-polariton condensates and calculate the warping of their polarization texture produced by TE-TM splitting of polariton band.
