Polaritons in microcavities can be viewed as dressed photons— light
interacts with electronic states in a solid in such a way that the
photons have an effective mass and repulsive interactions. Because
they are bosons, they can undergo Bose-Einstein condensation at low
temperature and become superfluid. It is now routine to make polariton
condensates, including in thermal equilibrium, with demonstrations of
such canonical effects as quantized vortices, Josephson oscillations,
and phase locking of two condensates. We can also now easily see
transport of polariton condensates over long distances of hundreds of
microns, allowing the possibility of polaritonic circuits. I will
present recent work on flow of polariton condensates in
one-dimensional channels and circular rings, and discuss recent work
on creating polariton condensates at room temperature.
*David Snoke* received his PhD in physics from the University of
Illinois at Urbana-Champaign. He has worked for The Aerospace
Corporation and was a visiting scientist and Fellow at the Max Planck
Institute. In 2006, he was elected a Fellow of the American Physical
Socieity with the citation, “For his pioneering work on the
experimental and theoretical understanding of dynamical optical
processes in semiconductor systems.” His research has focused on basic
processes and phase transitions of electrons, holes, including non
equilibrium dynamics of electron plasma and excitons, the Mott
transition from exciton gas to electron-hole plasma and Bose-Einstein
condensation of excitons and polaritons. His research group at the
University of Pittsburgh uses stress to trap excitons in confined
regions, similar to the way atoms are confined in traps for
Bose-Einstein condensation experiments.
