Abstract

Aubry Duality refers to a symmetry of some Schrodinger operators whereby a Fourier transform of an eigensolution of the operator is itself an eigensolution. In this talk we observe a form of Aubry Duality in some unitary operators connected to quantum walks. This talk is based on joint work with Chris Cedzich, Jake Fillman and Zhenghe Zhang.
