Abstract
We prove that Schrödinger operators with meromorphic potentials H alphathetau n=u n+1+u n1+ fracgtheta+nalphaftheta+nalpha u n have purely singular continuous spectrum on the set E LE deltaalpha theta where delta is an explicit function and L is the Lyapunov exponent This extends results of Jitomirskaya and Liu Arithmetic spectral transitions for the Maryland model CPAM to appear for the Maryland model and of AvilaYou and Zhou Sharp Phase transitions for the almost Mathieu operator Preprint 2015 for the almost Mathieu operator to the general family of meromorphic potentials
