Physical Review Letters, 120(9), 097401. doi:10.1103/PhysRevLett.120.0974010031-90071079-7114 (eISSN)https://hdl.handle.net/20.500.11815/805We 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.097401eninfo:eu-repo/semantics/openAccessElectronic structureExciton polaritonSpin-orbit couplingCondensed Matter & Materials PhysicsEðlisfræðiÞéttefnisfræðiRafeindirSkautun (rafsegulfræði)info:eu-repo/semantics/articlePhysical Review Letters10.1103/PhysRevLett.120.097401
