Addressing Shape and Extent of Weyl cones in TaAs by Landau level spectroscopy
David Santos-Cottin, Jan Wyzula, Florian Le Mardelé +7
Tantalum arsenide, TaAs, is a prime example of a topological semimetal with two types of Weyl nodes, W1 and W2, whose bulk signatures have proven elusive. We apply Landau level spe…
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…
Optical conductivity signatures of open Dirac nodal lines
D. Santos-Cottin, M. Casula, L. de' Medici +7
We investigate the optical conductivity and far-infrared magneto-optical response of BaNiS, a simple square-lattice semimetal characterized by Dirac nodal lines that disperse e…
Landau level spectroscopy of PbSnSe topological crystalline insulator
Kristupas Kazimieras Tikuišis, Jan Wyzula, Lukáš Ohnoutek +8
We report on an infrared magneto-spectroscopy study of PbSnSe, a topological crystalline insulator. We have examined a set of samples, all in the inverted regime of ele…
