Site recurrence of open and unitary quantum walks on the line
Silas L. Carvalho, Leonardo F. Guidi, Carlos F. Lardizabal
We study the problem of site recurrence of discrete time nearest neighbor open quantum random walks (OQWs) on the integer line, proving basic properties and some of its relations w…
On the spectral Hausdorff dimension of 1D discrete Schrödinger operators under power decaying perturbations
Vanderlea R. Bazao, Silas L. Carvalho, César R. de Oliveira
We show that spectral Hausdorff dimensional properties of discrete Schröodinger operators with (1) Sturmian potentials of bounded density and (2) a class of sparse potentials are p…
A characterization of singular packing subspaces with an application to limit-periodic operators
Silas L. Carvalho, César R. de Oliveira
A new characterization of the singular packing subspaces of general bounded self-adjoint operators is presented, which is used to show that the set of operators whose spectral meas…
