Spectral analysis for a multi-dimensional split-step quantum walk with a defect

Mathematical Physics 2020-08-21 v1 math.MP

Abstract

This paper studies the spectrum of a multi-dimensional split-step quantum walk with a defect that cannot be analysed in the previous papers. To this end, we have developed a new technique which allow us to use a spectral mapping theorem for the one-defect model. We also derive the time-averaged limit measure for one-dimensional case as an application of the spectral analysis.
