Exciton Polaritons in a Two-Dimensional Lieb Lattice with Spin-Orbit Coupling.
نویسندگان
چکیده
We study exciton polaritons in a two-dimensional Lieb lattice of micropillars. The energy spectrum of the system features two flat bands formed from S and P_{x,y} photonic orbitals, into which we trigger bosonic condensation under high power excitation. The symmetry of the orbital wave functions combined with photonic spin-orbit coupling gives rise to emission patterns with pseudospin texture in the flat band condensates. Our Letter shows the potential of polariton lattices for emulating flat band Hamiltonians with spin-orbit coupling, orbital degrees of freedom, and interactions.

We theoretically demonstrate the interplay of uniform spin-orbit coupling and uniform Zeeman magnetic field on the topological properties of one-dimensional double well nano wire which is known as Su-Schrieffer-Heeger (SSH) model. The system in the absence of Zeeman magnetic field and presence of uniform spin-orbit coupling exhibits topologically trivial/non–trivial insulator depending on the h...
متن کاملMicrocavity polaritons in disordered exciton lattices
We investigate the interaction of excitons in a two-dimensional lattice and photons in a planar cavity in the presence of disorder. The strong exciton-photon coupling is described in terms of polariton quasiparticles, which are scattered by a disorder potential. We consider three kinds of disorder: i inhomogeneous exciton energy, ii inhomogeneous exciton-photon coupling, and iii deviations from...
متن کاملSpin-Orbit Coupling in Polariton Graphene: Optical Spin Hall Effect and Z Topological Insulator
We show that the TE-TM splitting of planar cavities leads to a special type of spin-orbit coupling for polariton graphene, a honeycomb superstructure formed by pillar microcavities, transforming into an emergent field with Dresselhaus symmetry at the Dirac points of the Brillouin zone. This transformation can be evidenced by the Optical Spin Hall effect. Under an applied magnetic field, polarit...
متن کاملAngular dependence of giant Zeeman effect for semi-magnetic cavity polaritons
The observation of spin-related phenomena of microcavity polaritons has been limited due to weak Zeeman effect of non-magnetic semiconductors. We demonstrate that the incorporation of magnetic ions into quantum wells placed in a non-magnetic microcavity results in enhanced effects of magnetic field on exciton-polaritons. We show that in such a structure the Zeeman splitting of exciton-polariton...
متن کاملTransmutation of skyrmions to half-solitons driven by the nonlinear optical spin Hall effect.
We show that the spin domains, generated in the linear optical spin Hall effect by the analog of spin-orbit interaction for exciton polaritons, are associated with the formation of a Skyrmion lattice. In the nonlinear regime, the spin anisotropy of the polariton-polariton interactions results in a spatial compression of the domains and in a transmutation of the Skyrmions into oblique half-solit...
