Topological antichiral surface states in a magnetic weyl photonic crystal

HIGHLIGHTS

• who: Xiang Xi from the (UNIVERSITY) have published the paper: Topological antichiral surface states in a magnetic Weyl photonic crystal, in the Journal: (JOURNAL) of 26/09/2022
• what: The authors report the experimental observation of antichiral surface states by constructing a 3D modified Haldane model in a magnetic Weyl photonic crystal with two pairs of frequency-shifted Weyl points (WPs). The authors demonstrate that the surface state iso-frequency contours of the A-type surface can evolve from a single open Fermi arc to a single surface Fermi loop and finally to a single . . .
