Phonon softening and slowing down of charge-density-wave fluctuations in BaNiAs
Yu Song, Shan Wu, Xiang Chen +7
BaNiAs is a nonmagnetic analogue of the iron pnictide superconductors, and in its tetragonal state exhibits an incommensurate charge-density-wave (IC-CDW) and a sizable ela…
In-plane Isotropy of the Low Energy Phonon Anomalies in YBaCuO
Sofia-Michaela Souliou, Kaushik Sen, Rolf Heid +8
We study the temperature dependence of the low energy phonons in the reciprocal plane of the highly ordered ortho-II YBaCuO cuprate high temperature su…
Short-range nematic fluctuations in Sr1-xNaxFe2As2 superconductors
Shan Wu, Yu Song, Yu He +10
Interactions between nematic fluctuations, magnetic order and superconductivity are central to the physics of iron-based superconductors. Here we report on in-plane transverse acou…
Phonon anomalies with doping in superconducting oxychlorides Ca2-xCuO2Cl2
Blair W. Lebert, Hajime Yamamoto, Masaki Azuma +6
We measure the dispersion of the Cu-O bond-stretching phonon mode in the high-temperature superconducting parent compound CaCuOCl. Our density functional theory calcula…
Phonon dispersion of MoS
Hans Tornatzky, Roland Gillen, Hiroshi Uchiyama +1
Transition metal dichalcogenides like MoS, MoSe, WS, and WSe have attracted enormous interest during recent years. They are van-der-Waals crystals with highly aniso…
Non-complicated EuTiO3 Structure
David S. Ellis, Hiroshi Uchiyama, Satoshi Tsutsui +3
A recently published paper [arXiv:1206.5417 ]showed strong incommensurate diffraction peaks in EuTiO3 around zone boundary R-points. We wish to convey that in our samples, and, it…
