    "abstract": "We discover the existence of vortex solitons supported by the surface between\ntwo optical lattices imprinted in Kerr-type nonlinear media. Such solitons can\nfeature strongly noncanonical profiles, and we found that their properties are\ndictated by the location of the vortex core relative to the surface. The\nrefractive index modulation forming the lattices at both sides of the interface\nresults in complete stability of the vortex solitons in wide domains of their\nexistence, thus introducing the first known example of stable topological\nsolitons supported by a surface.",
