Switchable Weyl nodes in topological Kagome ferromagnet Fe3Sn2
M. Yao, H. Lee, N. Xu +7
The control of topological quantum materials is the prerequisite for novel devices exploiting these materials. Here we propose that the room temperature ferromagnet Fe3Sn2, whose f…
Evidence of Coulomb interaction induced Lifshitz transition and robust hybrid Weyl semimetal in Td MoTe2
N. Xu, Z. W. Wang, A. Magrez +13
Using soft x-ray angle-resolved photoemission spectroscopy we probed the bulk electronic structure of Td MoTe2. We found that on-site Coulomb interaction leads to a Lifshitz transi…
Spin-resolved electronic response to the phase transition in MoTe
Andrew P. Weber, Philipp Rüßmann, Nan Xu +10
The semimetal MoTe is studied by spin- and angle- resolved photoemission spectroscopy to probe the detailed electronic structure underlying its broad range of response behavior…
Trivial topological phase of CaAgP and the topological nodal-line transition in CaAg(P1-xAsx)
N. Xu, Y. T. Qian, Q. S. Wu +14
By performing angle-resolved photoemission spectroscopy and first-principles calculations, we address the topological phase of CaAgP and investigate the topological phase transitio…
