SUMMARY:Semiconductor microcavities: from cold polariton condensates to po
 lariton lasing at room temperature - Dr. Pavlos Lagoudakis (University of 
 Southampton)

DESCRIPTION:Semiconductor microcavities (MCs) offer a unique system for pr
 oducing and probing coherent states of matter. The bosonic nature of polar
 itons\, the quasi-particles formed in these structures\, and their very li
 ght mass can lead to the formation of non-equilibrium Bose-Einstein conden
 sation. The interest in the fundamental properties of these structures is 
 closely followed by technological advances such as inversionless ultralow 
 threshold lasers\, and micro-OPOs. Current efforts are devoted to developi
 ng novel MC-based photonic devices with both large Rabi splitting and exci
 ton binding energy that can operate at room temperature. In this seminar\,
  I will present our most recent results on polariton lasing at room temper
 ature and on the spatio-temporal dynamics of polariton condensates.
