Recently, the research group on metamaterials and fiber optic devices at the College of Physics and Optoelectronic Engineering, HEU, conducted experiments using continuous twisted Weyl meta-crystals and observed Fermi arc reconstruction with angle. This groundbreaking work unveiled the unique phenomenon of aperiodic Fermi arc scattering. This achievement opens up possibilities for the continuous control of Fermi arcs and serves as a guiding framework for the design of new devices and information control methods. The research findings, titled "Twisted Photonic Weyl Metacrystals and Aperiodic Fermi Arc Scattering," were published online on March 18th in the internationally recognized journal Nature Communications.

The paper was a collaborative effort between HEU, the National University of Defense Technology, Tongji University, and Hunan University. WANG Yiyuan, a doctoral student from the College of Physics and Optoelectronic Engineering, HEU, class of 2020, served as the co-first author of the paper, with Professor SHI Jinhui, the supervisor, as the co-corresponding author. Professor ZHANG Shuang from the University of Hong Kong provided guidance, and the work received support from the Basic Research Enhancement Program and the National Natural Science Foundation of HEU.
