On the Dynamics of XY Spin Chains with Impurities

Published 27 Aug 2014 in quant-ph, math-ph, and math.MP | (1408.6338v2)

Abstract: We provide a theoretical set up for studying the dynamics in quantum spin chain models with inhomogeneous two-body interaction. We frame in our formalism models that can be mapped into a fermion system with a quadratic Hamiltonian. Local and global existence results of the dynamics are discussed.
