Pressure-induced excitations in the out-of-plane optical response of the nodal-line semimetal ZrSiS
J. Ebad-Allah, S. Rojewski, M. Vöst +9
The anisotropic optical response of the layered, nodal-line semimetal ZrSiS at ambient and high pressure is investigated by frequency-dependent reflectivity measurements for the po…
Optical conductivity of the type-II Weyl semimetal WTe under pressure
M. Krottenmüller, J. Ebad-Allah, V. Süss +2
Tungsten ditelluride WTe is a type-II Weyl semimetal with electronic properties highly sensitive to external pressure, as demonstrated by the superconductivity emerging under p…
Influence of magnetic ordering on the optical response of the antiferromagnetic topological insulator MnBiTe
M. Köpf, J. Ebad-Allah, S. Lee +2
The layered topological insulator MnBiTe has attracted great interest recently due to its intrinsic antiferromagnetic order, potentially hosting various topological phases.…
Indications for Lifshitz transitions in the nodal-line semimetal ZrSiTe induced by interlayer interaction
M. Krottenmüller, M. Vöst, N. Unglert +8
The layered material ZrSiTe is currently extensively investigated as a nodal-line semimetal with Dirac-like band crossings protected by nonsymmorphic symmetry close to the Fermi en…
Optical spectroscopy on the photo-response in multiferroic BiFeO at high pressure
F. Meggle, J. Ebad-Allah, J. Kreisel +1
The pressure dependence of light-induced effects in single-crystalline BiFeO is studied by optical spectroscopy. At low pressures, we observe three light-induced absorption fea…
Infrared spectroscopy study of the nodal-line semimetal candidate ZrSiTe under pressure: Hints for pressure-induced phase transitions
J. Ebad-Allah, M. Krottenmüller, J. Hu +3
We studied the effect of external pressure on the optical response of the nodal-line semimetal candidate ZrSiTe by reflectivity measurements. At pressures of a few GPa, the reflect…
