Charge dynamics in the Weyl semimetals NbIrTe and TaIrTe under pressure: Signatures of an electronic phase transition
M. Lamp, J. Ebad-Allah, A. Chmeruk +7
A high-pressure investigation of the Weyl semimetals NbIrTe and TaIrTe is presented, using infrared spectroscopy supplemented by density functional theory calculations. The…
Signatures of van Hove singularities in the anisotropic in-plane optical conductivity of the topological semimetal NbSiTe
J. Ebad-Allah, A. A. Tsirlin, Y. L. Zhu +2
We present a temperature-dependent infrared spectroscopy study on the layered topological semimetal NbSiTe combined with density-functional theory (DFT) calculations of the…
In-plane and out-of-plane optical response of the nodal-line semimetals ZrGeS and ZrGeSe
J. Ebad-Allah, S. Rojewski, Y. L. Zhu +2
Polarization-dependent reflectivity measurements were carried out over a broad frequency range on single-crystalline ZrGeSe and ZrGeS compounds, which are closely related to the pr…
Ferromagnetic MnBi4Te7 obtained with low concentration Sb doping: A promising platform for exploring topological quantum states
Y. D. Guan, C. H. Yan, S. H. Lee +11
The tuning of magnetic phase, chemical potential, and structure is crucial to observe diverse exotic topological quantum states in (m = 0, 1, 2, & 3). Here…
Infrared study of the layered, magnetic insulator Mn(BiSb)Te at low temperatures
M. Köpf, S. H. Lee, H. Kumar +2
Topological insulators with intrinsic magnetic ordering, potentially hosting rare quantum effects, recently attracted extensive attention. MnBiTe is the first established e…
Influence of magnetic ordering on the optical response of the antiferromagnetic topological insulator MnBiTe
M. Köpf, J. Ebad-Allah, S. Lee +2
