Popis: We disclose a class of stable nonlinear traveling waves moving at specific constant velocities within symmetric two-dimensional quantum droplets. We present a comprehensive analysis of these traveling bubbles and find three qualitatively distinct regions within the family of solutions: well-separated phase singularities, singularities within the same dip in the density and rarefaction pulses without singularities. Then, we generalize the discussion to mildly unstable cases, incorporating higher order vortex-antivortex pairs and arrays of vortices that move cohesively with a common velocity within the fluid. In all cases, we provide analytic approximations that aid the understanding of the results in different regimes.
