Tunable Dirac nodal line in orthorhombic RuO
Ece Uykur, Oleg Janson, Victoria A. Ginga +3
Pressure evolution of RuO2 is studied using single-crystal x-ray diffraction in a diamond anvil cell, combined with \textit{ab initio} band-structure calculations. The tetragonal r…
Fermi-liquid behavior of non-altermagnetic RuO
Maxim Wenzel, Ece Uykur, Sahana Rößler +5
Presence of magnetism in potentially altermagnetic RuO has been a subject of intense debate. Using broadband infrared spectroscopy combined with density-functional band-structu…
Phonon and magnon dynamics across antiferromagnetic transition in 2D layered van der Waals material CrSBr
E. Uykur, A. A. Tsirlin, F. Long +6
We report temperature-dependent reflectivity spectra of the layered van der Waals magnet CrSBr in the far-infrared region. Polarization-dependent measurements resolve the vibration…
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 signatures of phase transitions and structural modulation in elemental tellurium under pressure
Diego Rodriguez, Alexander A. Tsirlin, Tobias Biesner +5
A room-temperature infrared spectroscopy study of elemental tellurium at pressures up to 8.44 GPa in the energy range 0.015-2 eV is reported. Optical signatures of the high-pressur…
Revealing excess protons in the infrared spectrum of liquid water
V. G. Artemov, E. Uykur, S. Roh +3
The most common species in liquid water, next to neutral HO molecules, are the HO and OH ions. In a dynamic picture, their exact concentrations depend on the time s…
