Evidence of 3D Dirac conical bands in TlBiSSe by optical and magneto-optical spectroscopy
F. Le Mardelé, J. Wyzula, I. Mohelsky +15
TlBiSSe is a rare realization of a 3D semimetal with a conically dispersing band that has an optical response which is well isolated from other contributions in a broad range of ph…
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…
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…
Carrier concentrations and optical conductivity of a band-inverted semimetal in two and three dimensions
Zoran Rukelj, Ana Akrap
Here we study the single-particle, electronic transport and optical properties of a gapped system described by a simple two-band Hamiltonian with inverted valence bands. We analyze…
Distinguishing the gapped and Weyl semimetal scenario in ZrTe: insights from an effective two-band model
Z. Rukelj, C. C. Homes, M. Orlita +1
Here we study the static and dynamic transport properties of a low energy two-band model proposed previously in E. Martino et al. [PRL 122, 217402 (2019), arXiv:1905.00280], with a…
Probing intraband excitations in ZrTe: a high-pressure infrared and transport study
D. Santos-Cottin, M. Padlewski, E. Martino +12
Zirconium pentatetelluride, ZrTe5, shows remarkable sensitivity to hydrostatic pressure. In this work we address the high-pressure transport and optical properties of this compound…
Manifestations of the electron-phonon interaction range in angle resolved photoemission spectra
J. Krsnik, V. N. Strocov, N. Nagaosa +4
Numerous angle resolved photoemission spectroscopy (ARPES) studies of a wide class of low-density metallic systems, ranging from doped transition metal oxides to quasi two-dimensio…
Low-energy excitations in type-II Weyl semimetal Td-MoTe2 evidenced through optical conductivity
D. Santos-Cottin, E. Martino, F. Le Mardele +5
Molybdenum ditelluride, MoTe2, is a versatile material where the topological phase can be readily tuned by manipulating the associated structural phase transition. The fine details…
Two-dimensional conical dispersion in ZrTe5 evidenced by optical spectroscopy
E. Martino, I. Crassee, G. Eguchi +8
Zirconium pentatelluride was recently reported to be a 3D Dirac semimetal, with a single conical band, located at the center of the Brillouin zone. The cone's lack of protection by…
