Abstract
A two-component quantum droplet refers to a combination of ultracold bosons that exhibit at-
tractive interactions, which are counteracted by quantum fluctuations to prevent collapse. Typically,
the investigation of two-component quantum droplets is conducted using a well-balanced combina-
tion. Nevertheless, the composition of the mixture may become unbalanced, leading to a decrease
in energy and a less stable binding of the droplet, potentially causing it to be immersed in a gaseous
environment. The primary objective of this study is investigate the impact of rotating on unbal-
anced droplets in an experimental setting. The analysis focuses on the examination of droplet in
imaginary-time simulation with rotation, specifically considering the variables of imbalance and ro-
tation frequency and also encompasses an examination of the vortices generated by rotating with
different frequencies.
