Physicists demonstrate polariton Bose-Einstein condensation using a planar waveguide

A team of physicists from CNR-Nanotec in Lecce, Università di Pavia, Princeton University and Université de Lyon has demonstrated Bose-Einstein condensation using a planar waveguide where semiconductor quantum wells were strongly coupled to a bound state in a continuum (BIC). In their paper published in the journal Nature, the group describes how they designed and built a BIC supported waveguide and used it to demonstrate polariton Bose-Einstein condensation.
