# Manipulating the rotational properties of a two-component Bose gas

## TL;DR

This paper investigates the rotational behavior of a two-component Bose-Einstein condensate, revealing multi-quantized vortices, absence of persistent currents, and a simple order parameter structure across various angular momenta.

## Contribution

It demonstrates the existence of multi-quantized vortices and the simple form of the order parameter in a two-component Bose gas under rotation, highlighting unique rotational properties.

## Key findings

- Presence of multi-quantized vortices due to interatomic interactions
- Absence of persistent currents in the system
- Simple structure of the order parameter across angular momenta

## Abstract

A rotating, two-component Bose-Einstein condensate is shown to exhibit vortices of multiple quantization, which are possible due to the interatomic interactions between the two species. Also, persistent currents are absent in this system. Finally, the order parameter has a very simple structure for a range of angular momenta.
