Non equilibrium phase transitions and Floquet Kibble-Zurek scaling

Non equilibrium phase transitions and Floquet Kibble-Zurek scaling

We study the slow crossing of non-equilibrium quantum phase transitions in periodically-driven systems. We explicitly consider a spin chain with a uniform time-dependent magnetic field and focus on the Floquet state that is adiabatically connected to the ground state of the static model. We find that this {\it Floquet ground …
