Expansion of cold atoms in the presence of disorder

Regular Seminar Boris Shapiro (Israel Institute of Technology)

16:00 Brunel U.
room M128

I will discuss the expansion of a Bose-Einstein condensate, released from a harmonic trap, in the presence of a random potential. The potential causes scattering of the condensate, preventing its free propagation. Under appropriate conditions some part of the condensate will get stuck (Anderson localization), whereas the rest will diffuse away. Expansion of a cold Fermi gas will be also discussed.
