[theochem-announce] Theochem Seminar TODAY, 4pm at Harvard

[Lee-Ping]

Dear All,

Professor Eric Bittner, from the University of Houston, is presenting a
theoretical chemistry seminar TODAY (Wednesday, April 6) from
4:00-6:00pm in the Pfizer lecture hall at Harvard University.  Please
take note of the location!

Title:  Bose Einstein condensation of Exciton/Polaritons in organic thin
film quantum wells: theory and experimental prospects.

Abstract:

  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.

Thank you!
