  We investigate the holographic dual of a probe scalar in an asymptotically
Anti-de-Sitter (AdS) disordered background which is an exact solution of
Einstein's equations in three bulk dimensions. Unlike other approaches to model
disorder in holography, we are able to explore quantum wave-like interference
effects between an oscillating or random source and the geometry. In the
weak-disorder limit, we compute analytically and numerically the one-point
correlation function of the dual field theory for different choices of sources
and backgrounds. The most interesting feature is the suppression of the
one-point function in the presence of an oscillating source and weak random
background. We have also computed analytically and numerically the two-point
function in the weak disorder limit. We have found that, in general, the
perturbative contribution induces an additional power-law decay whose exponent
depends on the distribution of disorder. For certain choices of the gravity
background, this contribution becomes dominant for large separations which
indicates breaking of perturbation theory and the possible existence of a phase
transition induced by disorder.
