Tkachenko modes and structural phase transitions of the vortex lattice of a two-component Bose-Einstein condensate
(American Physical Society, 2006)We consider a rapidly rotating two-component Bose-Einstein condensate (BEC) containing a vortex lattice. We calculate the dispersion relation for small oscillations of vortex positions (Tkachenko modes) in the mean-field ... -
Tkachenko modes of the square vortex lattice in a two-component Bose-Einstein condensate
(2006)We study Tkachenko modes of the square vortex lattice of a two-component Bose-Einstein condensate (BEC) in the mean-field quantum Hall regime, considering the coupling of these modes with density excitations. We derive the ... -
A variational approech to stationary and rotating Bose-Einstein condensates
(Bilkent University, 2006)After the experimental demonstration of Bose-Einstein condensation (BEC) in alkali gases [6, 7, 18], the number of theoretical and experimental papers on ultracold atomic physics increased enormously [48]. BEC experiments ...
