Higher-order Quantum Spin Hall Effect of Light
Biye Xie, Guangxu Su, Hong-Fei Wang +7
Band topology and related spin (or pseudo-spin) physics of photons provide us with a new dimension for manipulating light, which is potentially useful for information communication…
Thermal Stability Enhancement in Epitaxial α-Sn Films by Strain Engineering
Huanhuan Song, Jinshan Yao, Yuanfeng Ding +5
Exploring new topological materials with large topological nontrivial bandgaps and simple composition is attractive for both theoretical investigation and experimental realization.…
Symmetry-protected hierarchy of anomalous multipole topological band gaps in nonsymmorphic metacrystals
Xiujuan Zhang, Zhi-Kang Lin, Hai-Xiao Wang +5
Symmetry and topology are two fundamental aspects of many quantum states of matter. Recently, new topological materials, higher-order topological insulators, were discovered, featu…
3D nature of ZrTe band structure measured by high-momentum-resolution photoemission spectroscopy
H. Xiong, J. A. Sobota, S. -L. Yang +10
We have performed a systematic high-momentum-resolution photoemission study on ZrTe using eV photon energy. We have measured the band structure near the point, and quan…
Experimental observation of anisotropic Adler-Bell-Jackiw anomaly in type-II Weyl semimetal WTe crystals at the quasi-classical regime
Yang-Yang Lv, Xiao Li, Bin-Bin Zhang +10
The asymmetric electron dispersion in type-II Weyl semimetal theoretically hosts anisotropic transport properties. Here we observe the significant anisotropic Adler-Bell-Jackiw (AB…
Extremely large and significantly anisotropic magnetoresistance in ZrSiS single crystals
Yang-Yang Lv, Bin-Bin Zhang, Xiao Li +6
Recently, the extremely large magnetoresistance observed in transition metal telluride, like WTe, attracted much attention because of the potential applications in magnetic sen…
