X-ray charge-density studies a suitable probe for superconductivity?
Jan Langmann, Hasan Kepenci, Georg Eickerling +5
Case studies of -TiSe and YBaCuO have demonstrated that x-ray diffraction (XRD) studies can be used to trace even subtle structural phase transitions which…
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…
The structure of the superconducting high-pressure phase of ScCoC
Jan Langmann, Marcel Vöst, Dominik Schmitz +8
We investigate pressure-induced structural changes to the Peierls-type distorted low-temperature phase of the low-dimensional ScCoC as a possible origin of its pressure-enh…
Evidence for a soft-phonon-mode-driven Peierls-type distortion in ScCoC
Jan Langmann, Christof Haas, Emmanuel Wenger +3
We provide experimental and theoretical evidence for the realization of the Peierls-type structurally distorted state in the quasi-one-dimensional superconductor ScCoC by a…
Cooperative cluster-Jahn-Teller effect as a possible route to antiferroelectricity
K. Geirhos, J. Langmann, L. Prodan +8
We report the observation of an antipolar phase in cubic GaNbS driven by an unconventional microscopic mechanism, the cooperative Jahn-Teller effect of NbS molecula…
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…
