Coherent Atomic Soliton Molecules

TL;DR

This paper explores the formation and dynamics of coherent atomic soliton molecules in Bose-Einstein condensates, introducing novel bound states of vector matter-wave objects with potential applications in quantum matter control.

Contribution

It presents new types of matter-wave molecules formed by dark-bright soliton pairs and describes their unique properties in two-dimensional condensates.

Findings

Coherent matter-wave clusters can be constructed from dark-bright pairs.

Novel vector-bound states of solitons are identified in two dimensions.

The study advances understanding of soliton interactions in multicomponent BECs.

Abstract

We discuss the dynamics of interacting atomic bright solitons and dark bubbles in bulk immiscible Bose-Einstein condensates. Coherent matter-wave clusters can be constructed using dark-bright pairs with appropriate phases. In two dimensions we describe novel types of matter-wave molecules without a scalar counterpart that can be seen as bound states of vector objects.
