Low-temperature crossover in the momentum distribution of cold atomic gases in one dimension | | Vadim V. Cheianov

8 Aug 2004 | | Subject: | Other | cond-mat.other | | Abstract: | The momentum distribution function for the two-component 1D gases of bosons and fermions is studied in the limit of strong interatomic repulsion. A pronounced reconstruction of the distribution is found at a temperature much smaller than the Fermi temperature. This new temperature scale, which equals the Fermi temperature divided by the dimensionless coupling strength, is a feature of the two-component model and does not exist in the one-component case. We estimate the parameters relevant for the experimental observation of the crossover effect. | | Source: | arXiv, cond-mat/0408169 | | Services: | Forum | Review | PDF | Favorites | |
