1 Sep 2000 | | Journal: | Phys. Rev. A, Vol. 63, 013608 (2001) | | Subject: | Mesoscopic Systems and Quantum Hall Effect | cond-mat.mes-hall | | Abstract: | We theoretically investigate the use of red-detuned Laguerre-Gaussian (LG) laser beams of varying azimuthal mode index for producing toroidal optical dipole traps in two-dimensional atomic Bose-Einstein condensates. Higher-order LG beams provide deeper potential wells and tighter confinement for a fixed toroid radius and laser power. Numerical simulations of the loading of the toroidal trap from a variety of initial conditions is also given. | | Source: | arXiv, cond-mat/0008479 | | Services: | Forum | Review | PDF | Favorites | |
