Dipolar gases in quasi one-dimensional geometries

TL;DR

This paper investigates how dipole-dipole interactions influence the behavior of cold dipolar gases confined in quasi-one-dimensional geometries, revealing significant effects on scattering resonances and condensate properties.

Contribution

It demonstrates that dipolar interactions significantly alter scattering resonances and condensate characteristics in quasi-1D geometries, even when overshadowed by short-range forces in 3D.

Findings

Confinement-induced scattering resonances are affected by dipole-dipole interactions.

Dipolar interactions can drastically change quasi-1D condensate properties.

Effects are significant even when short-range interactions dominate in 3D.

Abstract

We analyze the physics of cold dipolar gases in quasi one-dimensional geometries, showing that the confinement-induced scattering resonances produced by the transversal trapping are crucially affected by the dipole-dipole interaction. As a consequence, the dipolar interaction may drastically change the properties of quasi-1D dipolar condensates, even for situations in which the dipolar interaction would be completely overwhelmed by the short-range interactions in a 3D environment.
