Large coupling asymptotics for the Lyapunov exponent of quasi-periodic Schr\"odinger operators with analytic potentials

We quantify the coupling asymptotics for the Lyapunov-exponent of a one-frequency quasi-periodic Schr"odinger operator with analytic potential sampling function. The result refines the well-known lower bound of the Lyapunov-exponent by Sorets and Spencer.
