Polariton condensation in $S$- and $P$-flatbands in a two-dimensional Lieb lattice

Sebastian Klembt, Tristan H. Harder, Oleg A. Egorov +6

We study the condensation of exciton-polaritons in a two-dimensional Lieb lattice of micropillars. We show selective polariton condensation into the flatbands formed by S and P$_{x…
