Universal response of the type-II Weyl semimetals phase diagram
P. RüÃmann, A. P. Weber, F. Glott +11
The discovery of Weyl semimetals represents a significant advance in topological band theory. They paradigmatically enlarged the classification of topological materials to gapless…
Unusual Shubnikov-de Haas oscillations in BiTeCl
C. Martin, A. V. Suslov, S. Buvaev +5
We report measurements of Shubnikov-de Haas (SdH) oscillations in single crystals of BiTeCl at magnetic fields up to 31 T and at temperatures as low as 0.4 K. Two oscillation frequ…
BiTeCl and BiTeBr: a comparative high-pressure optical study
I. Crassee, F. Borondics, M. K. Tran +8
We here report a detailed high-pressure infrared transmission study of BiTeCl and BiTeBr. We follow the evolution of two band transitions: the optical excitation between two R…
Discovery of Weyl semimetal state violating Lorentz invariance in MoTe2
N. Xu, Z. J. Wang, A. P. Weber +16
A new type of Weyl semimetal state, in which the energy values of Weyl nodes are not the local extrema, has been theoretically proposed recently, namely type II Weyl semimetal. Dis…
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…
Optical properties of BiTeBr and BiTeCl
A. Akrap, J. Teyssier, A. Magrez +4
We present a comparative study of the optical properties - reflectance, transmission and optical conductivity - and Raman spectra of two layered bismuth-tellurohalides BiTeBr and B…
