*Bose Einstein condensation of Exciton/Polaritons in organic thin film
quantum wells: theory and experimental prospects. *
Recent experiments on thin-film microcavities give evidence of Bose
condensation of exciton-polariton states. Inspired by these observations,
we consider the possibility that such exotic ``half-light/half matter"
states could be observed in thin-film organic semiconductors where the
oscillator strength is generally stronger than in inorganic systems. In my
talk, I present a theoretical model and simulations of macroscopic
exciton-polartiton condensates in anthracene thin films sandwiched within a
micro-meter scale resonant cavity and establish criteria for the conditions
under which BEC could be achieved in these systems.
