Gross-Pitaevski equation and resonances in Bose-Einstein condensates
João da Providência, Asaad R. Sakhel, F. Bary Malik +1 more
The investigation provides a criterion for the occurrence of resonances for the scattering by potentials. The Gross-Pitaevski equation, used in describing physical properties in Bose-Einstein condensates, is not compatible with the occurrence of the observed resonances. On the other hand, Geltman-Bambini and Krauss-Stevens potentials could fulfill this criterion.
