Exciton Polaritons in a Two-Dimensional Lieb Lattice with Spin-Orbit Coupling
Exciton Polaritons in a Two-Dimensional Lieb Lattice with Spin-Orbit Coupling
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 …
