Steady state of a driven quasi-one-dimensional Mott insulator with spin-orbital separation

We consider a periodically driven quasi-one-dimensional Mott insulator with spin-orbital separation. To understand the emerging steady state we employ a combination of Floquet theory and numerical methods based on integrability to treat the time-dependent perturbation of the spin ladder describing the low-energy sector. We discuss our results in connection to pump-probe experiments on the one dimensional spin-orbital chain compound Sr$_2$CuO$_3$.
