title: Talbot effect in a quadratic-index medium studied with two-variable Hermite polynomials and entangled states.
abstract: We have found the new eigenmodes, two-variable Hermite polynomials, exist in propagating plane waves in quadratic-index media and that a two-dimensional Talbot effect can be demonstrated with these modes.
