Title: Disordered quantum critical fixed points from holography
Abstract: I will show that in holographic theories, adding disorder whose scaling dimension is just below the Harris criterion triggers a flow to a stable fixed point with finite disorder strength. The effect can be understood both by solving the bulk equations of motion, and in simple cases by field theoretic 1-loop arguments. In holography, these methods also work for finite density field theories, where I will describe transport properties of the IR disordered fixed point.
