HET-Discovery seminar by Koenraad Schalm

Random potentials, string theory and condensed matter: Disorder and conductivity in holographic metals.

I will discuss some of the insights gained into strongly correlated condensed matter systems through holography. I will focus in particular on how heat and charge transport in such strongly coupled systems are affected by random impurities. A key insight will be the applicability of a hydrodynamic description. In the holographic dual this is captured by universal horizon physics. Excitingly three recent experiments detect such hydrodynamic flow inside electronic systems. No deep knowledge of condensed matter physics is assumed.
