Boundary-Robust Transmission Asymmetry as a Topological Signature in Open Floquet Lattices
Ren Zhang, Xiao-Yu Ouyang, Xu-Dong Dai +1
We identify a boundary-robust topological signature of open Floquet lattices: although nonadiabatic boundaries strongly reshape the transmission lineshape, the integrated left--rig…
Scattering-state theory of open Floquet lattices: transfer matrices, branch openness, and robust asymmetry
Ren Zhang, Xiao-Yu Ouyang, Xu-Dong Dai +1
We establish a scattering-state theory for open one-dimensional Floquet lattices based on a frequency-domain transfer-matrix formulation. For real quasienergy, the conjugate-symple…
Electromagnetic responses of bilayer excitonic insulators: from exciton London equations to dipole and inverse dipole Hall effects
Yuelin Shao, Hao Shi, Xi Dai
We develop a microscopic theory of the linear electromagnetic response of bilayer excitonic insulators relevant to electron-hole double-layer systems. Using a self-consistent Hartr…
Two-dimensional moiré phonon polaritons
Hao Shi, Chu Li, Ding Pan +1
Phonon polaritons (PhPs) are hybrid light-matter modes. We investigate them in two-dimensional (2D) materials with twisted moiré structures, revealing that the moiré potential crea…
