Wigner-localized states in spin-orbit-coupled bosonic ultracold atoms with dipolar interaction

TL;DR

This paper demonstrates that Rashba-like spin-orbit coupling significantly enhances dipole-dipole interactions in bosonic ultracold systems, enabling Wigner localization at lower dipole strengths than previously possible.

Contribution

It reveals how spin-orbit coupling facilitates Wigner localization in dipolar bosonic systems at reduced interaction strengths.

Findings

Spin-orbit coupling enhances dipole interactions

Wigner localization occurs at lower dipole moments

Potential for experimental realization of localized states

Abstract

We investigate the occurence of Wigner-localization phenomena in bosonic dipolar ultracold few-body systems with Rashba-like spin-orbit coupling. We show that the latter strongly enhances the effects of the dipole-dipole interactions, allowing to reach the Wigner-localized regime for strengths of the dipole moment much smaller than those necessary in the spin-orbit-free case.
