Furthermore, owing to the stretched electromagnetic waves in the ENZ media, ENZ Fano resonance has geometry-independent characteristics and can even be attained on a subwavelength scale. With the assistance of the Fabry-Perot mode, the background relative permeability of waveguide ENZ media can be engineered, experimentally validating the concept of ENZ Fano resonance.

Our scheme requires dN photons, which is the minimal required photon number, with substantially improved success probability from previous schemes.

We also observe the pseudomagnetic field-induced boundary states near the diagonal corners, which are quite different from conventional higher order topological corner states.

Postpump there is a quick reduction of the optical weight but a very slow recovery of the magnetic order-the difference is attributed to weak interlayer exchange in Sr_{2}IrO_{4} delaying the recovery of three-dimensional magnetic order. We suggest that the effect has a very different and more fundamental origin. Combining spatiotemporal mean field dynamics and Langevin dynamics on the photoexcited Mott-Hubbard insulator, we show that the timescale difference is not a dimensional effect but is intrinsic to charge dynamics versus order reconstruction in a correlated system. In two dimensions, we obtain a short, almost pump-fluence-independent timescale for charge dynamics, while recovery time of magnetic order involves domain growth and increases rapidly with fluence.
