    "abstract": "We put forward the existence of a rich variety of fully stationary vortex\nstructures, termed H-clusters, made of an increasing number of vortices nested\nin paraxial wave fields confined by trapping potentials. However, we show that\nthe constituent vortices are globally linked, rather than products of\nindependent vortices. Also, they always feature a monopolar global wave front\nand exist in nonlinear systems, such as Bose-Einstein condensates. Clusters\nwith multipolar global wave fronts are non-stationary or at best flipping.",
