Abstract

We study the multi-dimensional operator (Hxu)n=mn=1um+f(Tn(x))un(H_x u)_n=\sum_{|m-n|=1}u_{m}+f(T^n(x))u_n, where TT is the shift of the torus \Td\T^d. When d=2d=2, we show the spectrum of HxH_x is almost surely purely continuous for a.e. α\alpha and generic continuous potentials. When d3d\geq 3, the same result holds for frequencies under an explicit arithmetic criterion. We also show that general multi-dimensional operators with measurable potentials do not have eigenvalue for generic α\alpha.
