Matter Wave Interference Pattern in the collision of bright solitons (Bose Einstein condensates) in a time dependent trap

TL;DR

This paper demonstrates that matter wave interference patterns can be observed in colliding bright solitons within Bose-Einstein condensates without requiring free ballistic expansion, by tuning scattering length and trap parameters.

Contribution

It introduces a method to observe interference patterns in bright soliton collisions without free expansion, using time-dependent trapping and scattering length adjustments.

Findings

Interference patterns are observable in bright soliton collisions.

Proper tuning of scattering length and trap enables interference observation.

No free ballistic expansion needed for interference detection.

Abstract

We show that it is possible to observe matter wave interference patterns in the collision of bright solitons (Bose Einstein condensates) without free ballistic expansion for suitable choices of scattering length and time dependent trap.
