Scope
Long-range interactions are present in various problems, spreading from the dipolar excitations in solid state systems to Rydberg atoms in optical lattices, trapped ions or in the models of localization of light or sound.
Until very recently, the Anderson localization in such systems present even in low dimensions was believed to be straightforwardly understood by the standard methods, such as resonance counting and the locator expansion. On the other hand, the so-called non-ergodic delocalized (multifractal) states were believed to be an interesting, but marginally present only precisely at the Anderson transition point.
Recently, both these points have been challenged: both the entire phases of non-ergodic delocalized states and the Anderson localization beyond the convergence of the locator expansion have been found in long-range models. Therefore the understanding of these counterintuitive effects of correlations on Anderson localization as well as their interplay with Bethe-ansatz integrability, anisotropy, or time-reversal symmetry breaking are in the focus of the workshop, as both these directions are poorly developed and attract an increasing number of researchers to the field.
The main aim of the workshop is to find connections between a universal random-matrix description (including ergodicity-breaking phenomena and localization problems in many-body systems and the ones on random graphs), on one hand, and the model computer simulations and real experiments in many-body systems, on the other.
