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…
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…
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 com…
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…
Charge density waves and soft phonon evolution in the superconductor BaNi(AsP)
Tom Lacmann, Sofia-Michaela Souliou, Fabian Henssler +8
The superconductor BaNiAs exhibits a soft-phonon-driven, incommensurate charge density wave (I-CDW) which is accompanied by a small orthorhombic structural phase transition…
Visualization of defect-induced interband proximity effect at the nanoscale
Thomas Gozlinski, Qili Li, Rolf Heid +6
The vast majority of superconductors have more than one Fermi surface, on which the electrons pair below the critical temperature , yet their superconducting behavior can be w…
Charge-density-wave quantum critical point under pressure in 2-TaSe
Yuliia Tymoshenko, Amir-Abbas Haghighirad, Rolf Heid +13
Suppressing of an ordered state that competes with superconductivity is one route to enhance superconducting transition temperatures. Whereas the effect of suppressing magnetic sta…
The influence of phonon symmetry and electronic structure on the electron-phonon coupling momentum dependence in cuprates
Maryia Zinouyeva, Rolf Heid, Giacomo Merzoni +16
The experimental determination of the magnitude and momentum dependence of electron-phonon coupling (EPC) is an outstanding problem in condensed matter physics. The intensity of ph…
Absence of spin-orbit-coupling-induced effects on lattice dynamics in CePt3Si
S. Krannich, D. Lamago, D. Manske +5
Motivated by model calculations for the heavy fermion superconductor CePt3Si predicting phonon anomalies because of anti-symmetric spin-orbit coupling we performed a detailed exper…
