CPT Student Seminar: Holographic Diffusion

Presented by Vaios Ziogas, Durham University
30 October 2017 17:00 in OC218

In this talk I will consider transport of conserved charges in strongly coupled quantum systems with broken translations, using holographic techniques. Such systems are relevant in condensed matter physics in the context of spontaneous symmetry breaking as well as in the context of
momentum relaxation through a lattice. After introducing the relevant concepts, I will give the precise identification of the hydrodynamic modes that diffuse heat and electric charge. As an aside, in the case of explicit breaking I will connect with previous results of DC conductivities from black holes horizons via an Einstein relation for the diffusion constants.
