Abstract

Since its discovery in 1986, high temperature superconductivity has frustrated experimentalists and theorists alike. The frustration comes from the fact that since the interactions are strong, none of the simple cartoon models based on the standard theory of metals apply. Consequently, there is no clear way of interpreting experiments. Further, as there is no agreed-upon way of solving problems in which the interactions are strong, theorists continue to make progress largely based on the strength of their personalities, that is, proof by intimidation. I will describe a new approach to the strongly correlated problem based on a mapping to a gravitational dual. I will emphasize the rudiments of this mapping focusing on the origins of this new approach and give examples of how it has been applied to the classic Mott problem and superconductivity.
