  Abstract:
We present an analytic solution of a Vaidya-charged black hole with hyperscaling violating factor in an Einstein-Maxwell-Dilaton model, where the scalar potential is key to the existence of a solution. By making use of this result we will study the process of thermalization after a global quench in a theory whose gravitational description is provided by the resultant solution. In particular we shall probe the system by entanglement entropy and show that it exhibits certain scaling behaviours during the process.
