Absence of Absolutely Continuous Spectrum for Generic Quasi-Periodic Schrodinger Operators on the Real Line


الملخص بالإنكليزية

We show that a generic quasi-periodic Schrodinger operator in $L^2(mathbb{R})$ has purely singular spectrum. That is, for any minimal translation flow on a finite-dimensional torus, there is a residual set of continuous sampling functions such that for each of these sampling functions, the Schrodinger operator with the resulting potential has empty absolutely continuous spectrum.
