Centre for Particle Theory Colloquia: Conductivity at strong coupling from holography
18 November 2014 16:00 in CLC 202
The conductivity of strongly coupled materials, such as the high Tc superconductors, exhibit fascinating properties which are not compatible with those of a weakly coupled Fermi liquid. Signature properties include the linear dependence of the resistivity in temperature and also the anomalous scaling of the Hall angle with temperature. It has been argued that these properties are due to strong coupling and the lack of quasiparticles. I will discuss the way strongly coupled field theories conduct heat and electric current at finite density using holographic techniques and show the promise of this approach to capture some of these features.
