Title: Interacting gauge fields via Floquet driving
Abstract: Starting from the experiment of Chin’s group, I will first talk about the space-time symmetry of the Floquet driving and then present the numerical results of Floquet-Bloch calculations. The gauge field will be further derived via an effective Hamiltonian approach. Finally, the recent experimental advance on interacting gauge fields will be briefly discussed.
