Biexciton as a Feshbach resonance and Bose–Einstein condensation of paraexcitons in Cu2O
Paraexcitons, the lowest energy exciton states in Cu _2 O, have been considered a good system for realizing exciton Bose–Einstein condensation (BEC). The fact that their BEC has not been attained so far is attributed to a collision-induced loss, whose nature remains unclear. To understand collisiona...
