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…

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…

Revisiting Nishimori multicriticality through the lens of information measures
Zhou-Quan Wan, Xu-Dong Dai, Guo-Yi Zhu
The quantum error correction threshold is closely related to the Nishimori physics of random statistical models. We extend quantum information measures such as coherent information…
