Collective Excitations of Bose-Einstein Condensates in a Double-Well Potential
Ippei Danshita, Kyota Egawa, Nobuhiko Yokoshi +1
We investigate collective excitations of Bose-Einstein condensates at absolute zero in a double-well trap. We solve the Bogoliubov equations with a double-well trap, and show that…

Bogoliubov Excitations in a Kronig-Penney Potential
Ippei Danshita, Susumu Kurihara, Shunji Tsuchiya
With use of the Kronig-Penney model, we study the excitation spectrum of a Bose-Einstein condensate in a one-dimensional periodic potential. We solve the Bogoliubov equations analy…
