Ballistic Transport for Discrete Multi-Dimensional Schrödinger Operators With Decaying Potential

David Damanik, Zhiyan Zhao

We consider the discrete Schrödinger operator $H=-\Delta +V$ on ${\ell }^2({\mathbb{Z}}^d)$ with a decaying potential, in arbitrary lattice dimension $d\in {\mathbb{N}}^{\ast }$, where $\Delta$ is the s…
