Propagation of the relativistic charged particle in an ultracold atomic gas with Bose-Einstein condensates
Bose-Einstein condensation relativistic charged particles energy losses
2010/11/25
We study theoretically some effects caused by a propagation of the charged particle in a dilute gas of alkali-metal atoms in the state with Bose-Einstein condensates. The energy change of the high-spe...
A Spectroscopic Method to Measure the Superfluid Fraction of an Ultracold Atomic Gas
Spectroscopic Method Superfluid Fraction of an Ultracold Atomic Gas
2010/11/19
We perform detailed analytical and numerical studies of a recently proposed method for a spectroscopic measurement of the superfluid fraction of an ultracold atomic gas [N. R. Cooper and Z. Hadzibabic...
