Bose Condensate in a Double-Well Trap: Ground State and Elementary Excitations
L. Salasnich, A. Parola, L. Reatto
We study the Bose-Einstein condensate in the MIT double-well trap. We calculate the ground state density profile of Na atoms and the Bogoliubov spectrum of the elementary ex…

Bosons in a Toroidal Trap: Ground State and Vortices
L. Salasnich, A. Parola, L. Reatto
We study the Bose-Einstein condensate (BEC) in a 3-D toroidal Mexican hat trap. By changing the parameters of the potential, or the number of bosons, it is possible to modify stron…
