Homogeneous Spectrum of Quasi-periodic Gevrey Schrödinger Operators with Diophantine Frequency
Published 25 Feb 2021 in math.DS, math-ph, math.MP, and math.SP | (2102.12851v2)
Abstract: We consider the quasi-periodic Schr\"odinger operator with the non-degenerate Gevrey potential for the Diophantine frequency. We prove that if the coupling number of the potential is large, then the spectrum is homogeneous.
