[en] Coherent backscattering, which is an enhancement of the backscattered intensity of a light going
through a medium made of point-like scatterers, is known as one of the most robust interference
effects. It has been shown, although it is nowadays not fully understood yet, that in the presence of
non-linearities, this enhancement turns to an inhibition. We propose to study that effect by means of a system in which we study the transport of a Bose-Einstein condensate through Aharonov-Bohm rings in the presence of interaction and disorder. We find that our system is indeed a good candidate to observe the coherent peak’s inversion and is also suitable for more feasible theoretical calculations than in the original case.
