Physicists demonstrate polariton Bose-Einstein condensation using a planar waveguide - Phys.org

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…
