Toeplitz algebras and spectral results for the one-dimensional Heisenberg model
Mondher Damak, Marius Mantoiu, Rafael Tiedra de Aldecoa
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 N. This class contains the Hamiltonian of the one-dimensional Heisenberg model.
