Few-body bound states in dipolar gases and their detection

TL;DR

This paper investigates the formation and stability of few-body bound states in dipolar gases confined to low-dimensional geometries, proposing detection methods and discussing implications for many-body physics.

Contribution

It introduces the concept of stable few-body complexes in dipolar gases within low-dimensional setups and proposes in situ detection schemes.

Findings

Attraction between molecules in different tubes can overcome repulsion.

Complexes with multiple molecules in the same tube are stable.

Detection schemes for these complexes are proposed.

Abstract

We consider dipolar interactions between heteronuclear molecules in a low-dimensional setup consisting of two one-dimensional tubes. We demonstrate that attraction between molecules in different tubes can overcome intratube repulsion and complexes with several molecules in the same tube are stable. In situ detection schemes of the few-body complexes are proposed. We discuss extensions to the case of many tubes and layers, and outline the implications of our results on many-body physics.
