EuCdAs: a magnetic semiconductor
D. Santos-Cottin, I. Mohelský, J. Wyzula +18
EuCdAs is now widely accepted as a topological semimetal in which a Weyl phase is induced by an external magnetic field. We challenge this view through firm experimental ev…
Nodal-line driven anomalous susceptibility in ZrSiS
Bruno Gudac, Markus Kriener, Yuriy V. Sharlai +6
We demonstrate a unique approach to test the signature of the nodal-line physics by thermodynamic methods. By measuring magnetic susceptibility in ZrSiS we found an intriguing temp…
Lorentz-boost-driven magneto-optics in a Dirac nodal-line semimetal
J. Wyzula, X. Lu, D. Santos-Cottin +13
Optical response of crystalline solids is to a large extent driven by excitations that promote electrons among individual bands. This allows one to apply optical and magneto-optica…
Quantum oscillations of the magnetic torque in the nodal-line Dirac semimetal ZrSiS
F. Orbanić, M. Novak, Z. Glumac +3
We report a study of quantum oscillations (QO) in the magnetic torque of the nodal-line Dirac semimetal ZrSiS in the magnetic fields up to 35 T and the temperature range from 40 K…
Optical conductivity of the type-II Weyl semimetal TaIrTe
F. Le Mardelé, D. Santos-Cottin, E. Martino +7
TaIrTe is an example of a candidate Weyl type-II semimetal with a minimal possible number of Weyl nodes. Four nodes are reported to exist a single plane in -space. The exist…

Yuichiro Ando, Takahiro Hamasaki, Takayuki Kurokawa +7
We detected the spin polarization due to charge flow in the spin non-degenerate surface state of a three dimensional topological insulator by means of an all-electrical method. The…
Large linear magnetoresistance in the Dirac semimetal TlBiSSe
Mario Novak, Satoshi Sasaki, Kouji Segawa +1
The mixed-chalcogenide compound TlBiSSe realizes a three-dimensional (3D) Dirac semimetal state. In clean, low-carrier-density single crystals of this material, we found Shubnikov-…
Instantaneous Photon Drag Currents in Topological Insulators
Yoshito Onishi, Zhi Ren, Mario Novak +3
Topological insulator materials have been extensively studied in the field of condensed matter physics because nontrivial topology in the electronic state gives rise to a novel spi…
Bulk topological insulators as inborn spintronics detectors
