Title: Disorder and Interactions in Electronic Systems

Abstract: This talk is a review of the basic ideas of the physical phenomena that take place in disordered conductors due to the combination of quantum
interference and interaction between the electrons. We will focus on the zero-bias anomalies in the tunneling density of states, which give the
simplest example of a new quantitative physics that arises due to this combination. We will discuss both the connection of these anomalies with
the famous Anderson orthogonality catastrophe and discuss the role of Friedel oscillations in charge density. We will compare the anomalies in
clean and disordered cases in order to understand better the role of disorder. We will also try to establish connection of this general picture
with such paradigms as Landau Fermi liquid and one-dimensional Luttinger liquid.
