We investigate the stability and characteristics of vortex quantum droplets (QDs) with particle imbalance and different topological charges S ± in two components formed by binary Bose–Einstein condensates trapped in a ring potential. Two types of binary vortex QDs including semi-vortex (SV) and mixed-vortex (MV) QDs can be stable up to at least S − = 14 with the help of the ring potential. It is worth noting that, for a given number of particles in the binary vortex QDs, the more particles are concentrated in the zero-vorticity and lower-vor...
