Atomic Physics Seminars

ics Joint Seminar - Atomic/Condensed Matter

3:30 PM
Physics Building, Room 204

University of Amsterdam
"Phases of Rotating Bosons"
ABSTRACT:
We discuss states of matter that arise when ultra-cold, Bose-condensed atoms are made to rotate. For not-too-high rotation, triangular vortex lattices have been observed. We discuss the nature of similar lattices for the case of bosons with 2 or 3 degenerate components. We also discuss the atomic quantum Hall states that are expected to form after a quantum melting of the vortex lattice at ultra-high rotation, and present experimental signaturesof such states.
