Description
This talk will focus on how holography can be applied to condensed matter physics. I will review the physics of zero sound in Fermi liquids, an excitation which resembles hydrodynamic sound but exists at low temperature. I will then discuss a class of holographic models which exhibit a phenomenon similar to zero sound. These holographic models describe systems which are most definitely not Fermi liquids, so the fact that they possess a zero sound-like excitation raises the question of whether other materials, in particular strange metals, may exhibit zero sound.
