Zero-dimensional spectral measures for quasi-periodic operators with analytic potential
The authors study one-dimensional discrete Schrödinger operators with potentials \(V(n)=\lambda f(\theta + \alpha n)\), where \(f\) is an analytic function. They prove that the spectral measures are zero-dimensional for large \(\lambda\) and irrational \(\alpha\).
