Abstract:	Recently, it has been discovered that the inclusion of the Lee-Huang-Yang (LHY) correction to the mean-field approximation of binary and dipolar atomic boson condensates effectively prevents collapse and gives rise to stable localized modes, referred to as quantum droplets (QDs), in both two and three dimensions (2D and 3D). Notably, investigations have demonstrated that incorporating this interaction into vortices also contributes to the stabilization of self-bound vortex modes. This report presents a summary of the theoretical findings concerning 3D and quasi-2D vortex QDs. Specifically, we present stable vortex states for vortex QDs in binary and dipolar Bose-Einstein condensates, both in unconfined space and in anisotropic semidiscrete space.
