Coherent Backscattering of Bose-Einstein Condensates in Two-Dimensional Disorder Potentials
Coherent Backscattering of Bose-Einstein Condensates in Two-Dimensional Disorder Potentials
We study quantum transport of an interacting Bose-Einstein condensate in a two-dimensional disorder potential. In the limit of a vanishing atom-atom interaction, a sharp cone in the angle-resolved density of the scattered matter wave is observed, arising from constructive interference between amplitudes propagating along reversed scattering paths. Weak interaction transforms …
