Title : “Dynamics of periodically driven spin systems”
Speaker : Tista Banerjee (Supervisor- Prof. K. Sengupta), IACS
Date : 05th September, 2025 (Friday)
Time : 15:00 hours (IST)
Abstract : 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 transverse field Ising model. Next, I will discuss the role of such emergent approximate conservation laws in the possibility of observing the Mpemba effect in
a class of periodically driven many-body interacting quantum systems.
In the last part of the talk, I will discuss constructing a generic Floquet protocol which results in an exact Floquet flat band for an interacting many-body quantum system. I conclude by discussing the robustness of the flat band structure when we slightly perturb the drive parameters away from the exact conditions which lead to this exact Floquet flat band.
All are cordially invited to attend the Defense.
