- In this paper, we consider the following nonlinear disordered Stark model: $${\bf i}\partial_tu_n+δ(u_{n+1}+u_{n-1})+nu_n+v_nu_n+ε|u_n|^{2}u_n=0,\quad n\in\mathbb{Z}.$$ By employing the diagonalization of the associated linear operators and the KAM theory for nonlinear Hamiltonian systems, we establish that for parameters $δ$ and $\varepsilon$ in a reasonable range, and for most realization of random variables $v=\{v_n\}_{n \in \mathbb{Z}}$, there exist time quasi-periodic and spatially localized states that exhibit arbitrary power-law spatial decay.
