[كتاب][B] Bose–Einstein condensation in dilute gases

CJ Pethick, H Smith - 2008‏ - books.google.com
Since an atomic Bose-Einstein condensate, predicted by Einstein in 1925, was first
produced in the laboratory in 1995, the study of ultracold Bose and Fermi gases has become …

Collective excitations of a degenerate gas at the BEC-BCS crossover

M Bartenstein, A Altmeyer, S Riedl, S Jochim, C Chin… - Physical review …, 2004‏ - APS
We study collective excitation modes of a fermionic gas of Li 6 atoms in the BEC-BCS
crossover regime. While measurements of the axial compression mode in the cigar-shaped …

First and second sound in a strongly interacting Fermi gas

E Taylor, H Hu, XJ Liu, LP Pitaevskii, A Griffin… - Physical Review A …, 2009‏ - APS
Using a variational approach, we solve the equations of two-fluid hydrodynamics for a
uniform and trapped Fermi gas at unitarity. In the uniform case, we find that the first and …
