Materials driven out of equilibrium by lasers and other dynamical fields provide an exciting research frontier in condensed mater physics. Realization of new quantum states including topological bands is possible with the help of Floquet engineering, i.e., control of quantum states by time periodical external fields [1]. Less understood is how strongly interacting systems such as correlated electronic materials behave in strong fields. In systems coupled to baths, heating and relaxation may balance and interesting nonequilibrium steady states can be realized. One approach to study this problem is to employ a quantum field theory that has a holographic dual. The D3/D7 model is a string theory derived system which describes three dimensional Dirac fermions interacting with a Coulomb force mediated by nonlinear bosons (SUSY QCD). This model shows many features similar to Dirac materials that can be examined in condensed matter experiments. When the system is driven by rotating electric fields, we can use a simple theoretical trick to map it to a static system [1,2] in the dual model. An effective black hole is formed that signals a transition from an insulator to a metal. It is intriguing to compare the results with those directly obtained from numerical approaches [4].
