Abstract
We present a novel class of stable nonlinear traveling waves that can exist within symmetric two-dimensional quantum droplets. We have made a comprehensive analysis of these topological bubbles characterizing distinct regions, classified by their velocity. We also generalize the study to unstable cases, incorporating higher-order vortex-antivortex pairs and arrays of vortices that can move with a common velocity through the fluid. Analytic approximations that aid the understanding of the results in different regimes are provided for all the cases.
