DESCRIPTION:\nCo-authors: Andrew Berridge (University College London)\, Jo
 el Moore (UC Berkeley)\, Shivaji Sondhi (Princeton)\, Julian Sonner (MIT)\
 , Ashwin Vishwanath (UC Berkeley)\n The dynamical scaling of quantum criti
 cal systems in thermal equilibrium may be inherited in the driven steady-s
 tate\, leading to universal out-of-equilibrium behaviour. This attractive 
 notion has been demonstrated in a number of cases upon which holography ca
 n provide a revealing perspective and new results. I will discuss the appl
 ication of these ideas to a canonical 2-dimensional system driven out of e
 quilibrium by the application of a strong in-plane electric field. I will 
 focus upon the conditions required for the formation of a universal out of
  equilibrium steady state and its description using field theoretical and 
 holographic methods. Non-trivial out-of-equilibrium universality is partic
 ularly apparent in current noise\, which is dual to Hawking radiation in t
 he gravitational system. \n
