Abstract :

A quake is rumbling through the core of physics: the empiricisms of condensed matter physics and the mathematics of

string theory appear to have some deep relations. For the initiated this has an unusually strong allure, but since this

cocktail involves some of the most impenetrable areas of physics it is not easy to communicate the excitement to the

community at large. I will attempt to get some of it across by telling the story from the perspective of a condensed matter

theorist who learned string theory only quite recently. How string theory evolved from a reductionist’s enterprise into

some modern incarnation of statistical physics, equipped with general relativity turbo’s and quantum information boosters

in the form of the “AdS/CFT” holographic duality. How the universality of general relativity turned into a classification

method for phases of matter, including new forms of “quantum” matter characterized by dense quantum entanglements

on the macroscopic scale. How the latter reveal highly unusual traits having eerie resemblances with the mysterious

experimental observations, with as highlight the famous linear resistivity measured in the strange metal phase of

the high Tc superconducutors.
