Absence of wave operators for one-dimensional quantum walks

Mathematical Physics 2020-01-08 v1 math.MP

Abstract

We show that there exist pairs of two time evolution operators which do not have wave operators in a context of one-dimensional discrete time quantum walks. As a consequence, the borderline between short range type and long range type is decided.
