Description
In this talk, I will discuss transport phenomena in two classes of theories with holographic dual.
In the first part, I will discuss systems where U(1) current is non-conserved due to anomaly and illustrate
how one can show that the anomalous conductivities are non-renormalised in a large class of holographic RG flow.
The holographic RG flow we considered is generated by arbitrary dilaton potentials and arbitrary higher derivative
terms that do not break global symmetries, incorporating coupling constant corrections to the boundary theory
in an expansions around infinite coupling.
In the second part, I will focus on systems where translational symmetry is broken by slowly varying scalar fields
and show that the bound shear viscosity/entropy density is violate. I will also discuss how to understand the violation
in the language of forced fluid dynamics.
