A method for collective excitation of Bose-Einstein condensate

Karkuszewski, Zbyszek P. · Sacha, Krzysztof · Zakrzewski, Jakub

Original · EN

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.
