Vortex lattices in Bose-Einstein condensates: from the Thomas-Fermi to the lowest Landau level regime
M. Cozzini, S. Stringari, C. Tozzo
We consider a periodic vortex lattice in a rotating Bose-Einstein condensed gas, where the centrifugal potential is exactly compensated by the external harmonic trap. By introducin…

Stability diagram and growth rate of parametric resonances in Bose-Einstein condensates in one-dimensional optical lattices
C. Tozzo, M. Kraemer, F. Dalfovo
A Bose-Einstein condensate in an optical lattice exhibits parametric resonances when the intensity of the lattice is periodically modulated in time. These resonances correspond to…
