Toeplitz algebras and spectral results for the one-dimensional Heisenberg model
arXiv:math/0511006 · doi:10.1063/1.2222083
Abstract
We determine the structure of the spectrum and obtain non-propagation estimates for a class of Toeplitz operators acting on a subset of the lattice . This class contains the Hamiltonian of the one-dimensional Heisenberg model.
