A method for collective excitation of Bose-Einstein condensate
Zbyszek P. Karkuszewski, Krzysztof Sacha, Jakub Zakrzewski
Abstract
It is shown that by an appropriate modification of the trapping potential one may create collective excitation in cold atom Bose-Einstein condensate. The proposed method is complementary to earlier suggestions. It seems to be feasible experimentally --- it requires only a proper change in time of the potential in atomic traps, as realized in laboratories already.
