Three-fermion problems in optical lattices | | T. Luu

2 Jun 2006 | | Subject: | Other | | Abstract: | We present exact results for the spectra of three fermionic atoms in a single well of an optical lattice. For the three lowest hyperfine states of Li6 atoms, we find a Borromean state across the region of the distinct pairwise Feshbach resonances. For K40 atoms, nearby Feshbach resonances are known for two of the pairs, and a bound three-body state develops towards the positive scattering-length side. In addition, we study the sensitivity of our results to atomic details. The predicted few-body phenomena can be realized in optical lattices in the limit of low tunneling. | | Source: | arXiv, cond-mat/0606069 | | Other source: | [GID 378052] pmid17358531 | | Services: | Forum | Review | PDF | Favorites | |
