Ansatz from Non-Linear Optics Applied to Trapped Bose-Einstein Condensates
Murat Keceli, F. O. Ilday, M. O. Oktel
A simple analytical ansatz, which has been used to describe the intensity profile of the similariton laser (a laser with self-similar propagation of ultrashort pulses), is used as…

Tkachenko modes and structural phase transitions of the vortex lattice of a two component Bose-Einstein condensate
M. Keceli, M. O. Oktel
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 posit…
