Bose-Einstein condensation in semiconductors: myth or reality?

J. Kasprzak, M. Richard, R. AndrÃ©, L.S. Dang

Abstract

Bose-Einstein condensation, predicted for a gas of non interacting bosons in 1924 by Einstein, has been demonstrated for the first time in 1995 in a dilute gas of rubidium atoms at temperatures below 10^â€“6 K. In this work, it is shown that Bose-Einstein condensation can be achieved at around 15 â€“ 20 K in a solid state system by using microcavity polaritons, which are composite bosons of mass ten billion times lighter than that of rubidium atoms.
