Quantum Depletion of an Excited Condensate
Jacek Dziarmaga, Zbyszek P. Karkuszewski, Krzysztof Sacha
We analyze greying of the dark soliton in a Bose-Einstein condensate in the limit of weak interaction between atoms. The condensate initially prepared in the excited dark soliton s…
Simple method for excitation of a Bose-Einstein condensate
Bogdan Damski, Zbyszek P. Karkuszewski, Krzysztof Sacha +1
An appropriate, time-dependent modification of the trapping potential may be sufficient to create effectively collective excitations in a cold atom Bose-Einstein condensate. The pr…
A method for collective excitation of Bose-Einstein condensate
Zbyszek P. Karkuszewski, Krzysztof Sacha, Jakub Zakrzewski
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 complem…
