15 Oct 2002 | | Journal: | J.Phys. A36 (2003) 9045-9052 | | Subject: | Soft Condensed Matter | cond-mat.soft nucl-th quant-ph | | Abstract: | Small deviations from purely bosonic behavior of trapped atomic Bose-Einstein condensates are investigated with the help of the quon algebra, which interpolates between bosonic and fermionic statistics. A previously developed formalism is employed to obtain a generalized version of the Gross-Pitaeviskii equation. Two extreme situations are considered, the collapse of the condensate for attractive forces and the depletion of the amount of condensed atoms with repulsive forces. Experimental discrepancies observed in the parameters governing the collapse and the depletion of the condensates can be accounted for by universal fittings of the deformation parameter for each case. | | Source: | arXiv, cond-mat/0210310 | | Services: | Forum | Review | PDF | Favorites | |
