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…
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…
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…
