Direct measurement of polariton-polariton interaction strength in the Thomas-Fermi regime of exciton-polariton condensation
Direct measurement of polariton-polariton interaction strength in the Thomas-Fermi regime of exciton-polariton condensation
Bosonic condensates of exciton polaritons (light-matter quasiparticles in a semiconductor) provide a solid-state platform for studies of non-equilibrium quantum systems with a spontaneous macroscopic coherence. These driven, dissipative condensates typically coexist and interact with an incoherent reservoir, which undermines measurements of key parameters of the condensate. Here, we overcome this …
