Parkin,Claudia Felser,Chandra Shekhar +28 more
TL;DR: In this paper, the authors reported ultra-high electrical conductivity in MoP at low temperature, which has recently been established as a triple point fermion material, and they showed that the electrical resistivity is 6 nΩ cm at 2'K with a large mean free path of 11 microns.
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

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.
Journal ArticleDOI
Heusler, Weyl and Berry
TL;DR: In this article, the authors discuss the properties of Heusler compounds from a topological perspective and the connection between the topology and the symmetry properties, spin gapless semiconductors, magnetic compensated ferrimagnets, non-collinear order in ferromagnetic and ǫ-antiferromagnetic HeUsler compounds, anomalous Hall effect and magnetic antiskyrmions.
Journal ArticleDOI
Chiral topological semimetal with multifold band crossings and long Fermi arcs

Krieger,Vicky Süss,Marcus Schmidt,Pavel Dudin,Barry Bradlyn,Timur K. Kim,Thorsten Schmitt,Cephise Cacho,Claudia Felser,Vladimir N. Strocov,Yulin Chen +20 more
TL;DR: AlPt is shown to be a chiral topological material with four-fold and six-fold degeneracies in the band structure as discussed by the authors, which can be viewed as a higher spin generalization of Weyl fermions.
