Rotating quantum liquids crystallize

TL;DR

This paper demonstrates that small quantum systems under high rotation tend to form crystalline structures, regardless of particle statistics, approaching classical behavior in strongly correlated states.

Contribution

It reveals that rotation induces crystallization in small quantum systems, independent of particle type or spin, bridging quantum and classical behaviors.

Findings

Crystallization occurs in both bosonic and fermionic systems.

High rotation leads to localization similar to classical particles.

Spin does not affect the crystallization process.

Abstract

Small crystallites form when finite quantal systems are set highly rotating. This crystallization is independent of the statistics of the particles, and occurs for both trapped bosons and fermions. The spin degree of freedom does not change the tendency for localization. In a highly rotating state, the strongly correlated bosonic and fermionic systems approach to that of classical particles.
