Title:
Algebraic Localization of Disordered Long-Range Quantum Models

Abstract:
Several atomic, molecular, and optical systems, as well as certain condensed
matter models, exhibit long-range interactions that decay with distance 
r as a
power law 1/rα

In this talk, we will present recent results for the localization 
properties of
correlation functions of these long-range quantum models in the presence of
disorder. The latter is usually associated with exponential localization 
of wave
functions and correlations. We demonstrate that in most situations in 1D
power-law interactions imply algebraic decay of correlations. We will 
discuss
the generality of these results and their application to experiments in 
atomic
and molecular physics.
