Journal ArticleDOI
Discovery of topological Weyl fermion lines and drumhead surface states in a room temperature magnet
Ilya Belopolski,Kaustuv Manna,Daniel S. Sanchez,Guoqing Chang,Benedikt Ernst,Jiaxin Yin,Songtian S. Zhang,Tyler A. Cochran,Nana Shumiya,Hao Zheng,Bahadur Singh,Guang Bian,Daniel Multer,Maksim Litskevich,Xiaoting Zhou,Shin-Ming Huang,Baokai Wang,Tay-Rong Chang,Su-Yang Xu,Arun Bansil,Claudia Felser,Hsin Lin,M. Zahid Hasan,M. Zahid Hasan +23 more
TL;DR: In this paper, the authors used photoemission spectroscopy and quantum transport to elucidate the topology of the room temperature magnet Co2MnGa and observed sharp bulk Weyl fermion line dispersions indicative of nontrivial topological invariants present in the magnetic phase.

Journal ArticleDOI
Topological chiral crystals with helicoid-arc quantum states
Daniel S. Sanchez,Ilya Belopolski,Tyler A. Cochran,Xitong Xu,Jiaxin Yin,Guoqing Chang,Weiwei Xie,Kaustuv Manna,Vicky Süß,Cheng Yi Huang,Nasser Alidoust,Daniel Multer,Songtian S. Zhang,Nana Shumiya,Xirui Wang,Guang Qiang Wang,Tay-Rong Chang,Claudia Felser,Su-Yang Xu,Shuang Jia,Shuang Jia,Hsin Lin,M. Zahid Hasan,M. Zahid Hasan +23 more
TL;DR: The results demonstrate an electronic topological state of matter on structurally chiral crystals featuring helicoid-arc quantum states that could be used to detect a quantized photogalvanic optical response, the chiral magnetic effect and other optoelectronic phenomena predicted for this class of materials.

Zahid Hasan +25 more
TL;DR: In this paper, the authors used high-resolution scanning tunnelling microscopy to discover an unconventional chiral charge order in a kagome material, KV3Sb5, with both a topological band structure and a superconducting ground state.
Journal ArticleDOI
Giant and anisotropic many-body spin–orbit tunability in a strongly correlated kagome magnet
Jiaxin Yin,Songtian S. Zhang,Hang Li,Kun Jiang,Guoqing Chang,Bing-Jing Zhang,Biao Lian,Cheng Xiang,Cheng Xiang,Ilya Belopolski,Hao Zheng,Tyler A. Cochran,Su-Yang Xu,Guang Bian,Kai Liu,Tay-Rong Chang,Hsin Lin,Z. Y. Lu,Ziqiang Wang,Shuang Jia,Shuang Jia,Wen-Hong Wang,M. Zahid Hasan,M. Zahid Hasan +23 more
TL;DR: The tunability of this kagome magnet reveals a strong interplay between an externally applied field, electronic excitations and nematicity, providing new ways of controlling spin–orbit properties and exploring emergent phenomena in topological or quantum materials10–12.
