Contribution

It introduces a detailed analysis of collisional decay in driven BECs, highlighting deviations from typical s-wave halos and employing novel simulation and modeling approaches.

Findings

Decay products deviate from s-wave halo patterns

Classical field simulations effectively model the collisional manifold

Bloch state model explains the decay dynamics

Abstract

We study the collisional decay of a strongly driven Bose-Einstein condensate oscillating between two momentum modes. The resulting products of the decay are found to strongly deviate from the usual s-wave halo. Using a stochastically seeded classical field method we simulate the collisional manifold. These results are also explained by a model of colliding Bloch states.
