Evolution of charge-density-wave soft phonon modes in
Avishek Maity, Stephan Rosenkranz, Raymond Osborn +8
We investigated the lattice dynamics of quasi-two-dimensional Pd-intercalated in relation to its charge-density-wave (CDW) transitions by means of x-ray diffuse a…
Lattice Dynamics of LiFeAs studied by Inelastic Neutron Scattering and Density Functional Theory calculations
Akshay Tewari, Navid Qureshi, Rolf Heid +6
We investigated the lattice dynamics of the unconventional superconductor LiFeAs using inelastic neutron scattering experiments and density-functional theory (DFT) calculations. By…
Interplay of Charge and Magnetic Orders in SmNiC Mediated by Electron-Phonon Interaction
A. von Ungern-Sternberg Schwark, A. -A. Haghighirad, R. Heid +11
We investigate the interplay between charge density wave (CDW) instabilities and ferromagnetism in SmNiC using diffuse and inelastic x-ray scattering together with Raman spectr…
Strain-induced structural change and nearly-commensurate diffuse scattering in the model high-temperature superconductor HgBaCuO
Mai Ye, Wenshan Hong, Tom Lacmann +9
We investigate the strain response of underdoped HgBaCuO (Hg1201), by synchrotron X-ray diffraction and corresponding simulations of thermal diffuse scattering. The co…
Correlation between magnetism and lattice dynamics for cubic FeGe under pressure
R. A. Tonacatl-Monez, R. Heid, O. De la Peña-Seaman
This first-principles study investigates the structural, electronic, lattice dynamical properties, and electron-phonon coupling in ferromagnetic cubic B20 FeGe under applied pressu…
Soft Mode Origin of Charge Ordering in Superconducting Kagome CsVSb
Philippa Helen McGuinness, Fabian Henssler, Manex Alkorta +12
Charge-density-wave (CDW) order and superconductivity coexist in the kagome metals AVSb (A=K, Cs, Rb), raising fundamental questions about the mechanisms driving their inte…
