Implosions in Bose Einstein Condensates as a probe for quantum and thermal fluctuations
ORAL
Abstract
Understanding the nature of fluctuations within a Bose-Einstein Condensate poses a difficult experimental challenge. When a BEC initially with positive interactions is quenched to a large negative scattering length, it is known that the resulting gas will be unstable and begin to collapse. Any initial perturbations of the density will be amplified as they seed the ensuing implosions. Using a well understood initial perturbation provided by an optical lattice potential, we characterize the experimental signatures of the microscopic implosions. This sets the stage for future experiments where the implosions are seeded by intrinsic quantum or thermal fluctuations, and thus the implosions will become an experimental tool for measuring fluctuations in a BEC.
