Unitary long-time dynamics with quantum renormalization groups and Artificial Neural Networks — •Heiko Burau and Markus Heyl — Max Planck Institut für Physik komplexer Systeme, Dresden, Germany

The exponential growth of complexity in quantum mechanics limits, in general, the simulation of non-equilibrium dynamics in large closed systems to short or intermediate time scales. In this work we combine quantum renormalization group approaches with deep artificial neural networks (ANNs) for the description of the real-time evolution in strongly disordered quantum matter. We find that this allows us to accurately compute the long-time dynamics of many-body localized systems. Concretely, we use this approach to describe the spatioemporal buildup of many-body localized spin glass order in random Ising models.
