Bottle atom trapping configuration by optical dipole forces

The bottle beam configuration is a light field created by the interference of a pair of Laguerre–Gauss light beams with zero orbital angular momentum. In this work we show the theoretical study of the bottle beam as well as the use of this beam for the creation of a novel atom optical dipole trap namely the bottle atom trap. In such a trap the resulting dark trapping region is three-dimensional and has a cylindrical symmetry. These promising results show that this trap is a nice candidate for trapping Bose–Einstein condensates and may serve as an optical tweezer mechanism potentially useful for trapping micron-sized dielectric particles.
