Description
 
In this talk, I will try to convey how the interplay between emergent approximate conservation law and dissipation shapes the entanglement scaling properties of the steady state of a periodically driven quantum system. Next, I will discuss the role of these conservation laws in the possibility of observing the Mpemba effect in a class of periodically driven many-body interacting quantum systems.
These conservation laws appear at few parameters in the whole parameter regime of the system under consideration. Keeping this in mind, in the last part of the talk, I will try to construct some generic Floquet protocol which will result in an exact Floquet flat band for an interacting quantum many-body system. I will also discuss the robustness of this Floquet flat band if we slightly perturb the drive parameters away from the exact conditions that need to hold in order to get a Floquet flat band.
