Exact Fractional Revival in Spin Chains

Published 28 Jun 2015 in math-ph, math.MP, and quant-ph | (1506.08434v3)

Abstract: The occurrence of fractional revival in quantum spin chains is examined. Analytic models where this phenomenon can be exhibited in exact solutions are provided. It is explained that spin chains with fractional revival can be obtained by isospectral deformations of spin chains with perfect state transfer.
