Title：Quantum harmonic oscillator with time quasi-periodic perturbations: almost reducibility and growth of Sobolev norms

Abstract：For 1-d quantum harmonic oscillator perturbed by a time quasi-periodic polynomial of (x,-i\partial_x) of degree 2, we consider its almost reducibility. As an application, we show different behaviors of the solutions in Sobolev spaces. This is based on several joint works with Z. Liang, J. Luo and Q. Zhou.
