WebNov 29, 2024 · We theoretically investigate the optical focusing of a rubidium Bose-Einstein condensate onto a planar surface. Our analysis uses a Gaussian variational method that includes the effects of two-body atom-atom interactions and three-body recombination losses. The essential factors such as the width, peak density and atom loss rate of the … WebUsing the Crank-Nicholson method, we study the evolution of a Bose-Einstein condensate in an optical lattice and harmonic trap. The condensate is excited by displacing it from the center of the harmonic trap. The mean field plays an important role in the Bloch-like oscillations that occur after sufficiently large initial displacement.
WebCreating stable solitons or self-trapped modes in systems with a dimension higher than one remains a challenging and attractive problem in physics, both in theory and experiments [1,2].The main obstacle lies in the ubiquitous cubic nonlinearity, which could be the Kerr effect in optics [] or the intrinsic ones induced by two-body scattering in Bose–Einstein … WebDec 9, 2024 · The focusing of a propagating untrapped Bose-Einstein condensate is studied theoretically. We use a scaling solution method comprising a time-dependent scaling …
Webof Bose–Einstein condensates10,11, for storing information. A Bose–Einstein condensate is fundamentally different from even very cold, non-condensed clouds. Bose–Einstein condensates are phase-coherent objects, and changes of the stored holographic imprint owing to atom dynamics do not lead to loss of information as in non-condensed WebDec 13, 2024 · Abstract We report on the all-optical production of Bose-Einstein condensates in microgravity using a combination of grey molasses cooling, light-shift engineering and optical trapping in a painted potential. Forced evaporative cooling in a 3-m high Einstein elevator results in 4×104 condensed atoms every 13.5 s, with a temperature …
