Description
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. In this setup of
reduced symmetry, I will give the precise identification of
the relevant 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.
