Abstract
We prove that Schr\"odinger operators with meromorphic potentials have purely singular continuous spectrum on the set , where is an explicit function, and is the Lyapunov exponent. This extends results of Jitomirskaya and Liu for the Maryland model and of Avila, You and Zhou for the almost Mathieu operator, to the general family of meromorphic potentials.
