Abstract

We prove the reducibility of quantum harmonic oscillators in R d perturbed by a quasi-periodic in time potential V (x , ω t) with logarithmic decay . By a new estimate built for solving the homological equation we improve the reducibility result by Grébert-Paturel(Annales de la Faculté des sciences de Toulouse : Mathématiques. 28 , 2019).
