Persistence under weak disorder of AC spectra of quasi-periodic Schrödinger operators on trees graphs.
M. Aizenman, S. Warzel Princeton University, Department of Mathematics
Abstract:
We consider radial tree extensions of one-dimensional quasi-periodic Schrödinger operators and establish the stability of their absolutely continuous spectra under weak but extensive perturbations by a random potential. The sufficiency criterion for that is the existence of Bloch–Floquet states for the one dimensional operator corresponding to the radial problem.
Key words and phrases:
Random operators, absolutely continuous spectrum, quasi-periodic cocycles, Bloch states.
