*ITAMP Lunch Seminar*
*Speaker:* Ivana Dimitrova (MIT)
*Date:* Monday, Feb 8th
*Time:* 12:00-1:00 pm
Includes Pizza.
*Title: *New regimes of superradiance in a symmetrically pumped BEC
*Abstract: *Superradiance is the collective scattering of light from a
group of particles. Bose Einstein condensates are particularly well-suited
to study superradiance in the form of collective Rayleigh scattering due to
their long coherence times. We have realized new regimes of superradiance
when a BEC is pumped by two noninterfering counterpropagating beams. For
small Rayleigh scattering rates, there is suppression of superradiance,
while for large Rayleigh scattering rates a new phase, similar to a
supersolid, is energetically favored. I will discuss our experimental
observations together with the theoretical prediction of a supersolid in
this system.
*Location: *B-106 @ Center for Astrophysics (60 Garden Street)
*Directions: *After entering the lobby of the CfA, turn right to enter the
hallway of the B building. In the hallway, turn right again, B-106 will be
at the end of the hallway on the left side.
