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...
Low-temperature thermodynamics of the unitary Fermi gas: superfluid fraction, first sound and second sound
Low-temperature thermodynamics of the unitary Fermi gas superfluid fraction first sound second sound
2011/1/10
We investigate the low-temperature thermodynamics of the unitary Fermi gas by introducing a
model based on the zero-temperature spectra of both bosonic collective modes and fermonic singleparticle ex...
