Propagation of Bose-Einstein Condensates in a Magnetic Waveguide

Gaseous Bose-Einstein condensates of 2-3 x 10(6) 23Na atoms were loaded into a microfabricated magnetic trap using optical tweezers. Subsequently, the condensates were released into a magnetic waveguide and propagated 12 mm. Single-mode propagation was observed along homogeneous segments of the waveguide. Inhomogeneities in the guiding potential arose from geometric deformations of the microfabricated wires and caused strong transverse excitations. Such deformations may restrict the waveguide physics that can be explored with propagating condensates. Finer perturbations to the guiding potential fragmented the condensate when it was brought closer to the surface.

Bistability of material waves in an atomic Bose-Einstein condensate in a magnetic interferometer

Nikolai N Rozanov, В. А. Смирнов, Sergey V. Fedorov

It is shown theoretically that, upon filling a ring cavity (a loop magnetic waveguide) with an atomic Bose-Einstein condensate (BEC), a hysteresis dependence of the atomic number density inside the cavity on the atomic flux introduced into the cavity from the outside appears. Main parameters of the measuring system being proposed are determined: the reflectance of the magnetic mirror through which the condensate is introduced, the length of the ring cavity, and the strength of the constant magnetic field governing the BEC velocity in the cavity.

We investigate the exact solutions of one-dimensional (1D) time-independent Gross–Pitaevskii equation (GPE), which governs a Bose–Einstein condensate (BEC) in the magnetic waveguide with a square-Sech potential. Both the bound state and transmission state are found and the corresponding spatial configurations and transport properties of BEC are analyzed. It is shown that the well-known absolute transmission of the linear system can occur in the considered nonlinear system.
