For a significant composition range, the suppression of the spin density wave transition temperature ($T_{\text{SDW}}$) in Cr- and Mn-substituted BaFe$_{2}$As$_{2}$ (CrBFA and MnBFA, respectively) coincides as a function of Cr/Mn content, despite the

Electron-momentum dependence of electron-phonon coupling underlies dramatic phonon renormalization in YNi2B2C

Autor: Philipp Kurzhals, Geoffroy Kremer, Thomas Jaouen, Christopher W. Nicholson, Rolf Heid, Peter Nagel, John-Paul Castellan, Alexandre Ivanov, Matthias Muntwiler, Maxime Rumo, Bjoern Salzmann, Vladimir N. Strocov, Dmitry Reznik, Claude Monney, Frank Weber

Publikováno v: Nature Communications, Vol 13, Iss 1, Pp 1-9 (2022)

Phonon anomalies are commonly attributed to Fermi-surface nesting or phonon anharmonicity, but these mechanisms do not apply in all cases. Here, the authors propose a new mechanism based on electron-momentum-dependent electron-phonon coupling in the

Electron-momentum dependence of electron-phonon coupling underlies dramatic phonon renormalization in YNi

Autor: Philipp, Kurzhals, Geoffroy, Kremer, Thomas, Jaouen, Christopher W, Nicholson, Rolf, Heid, Peter, Nagel, John-Paul, Castellan, Alexandre, Ivanov, Matthias, Muntwiler, Maxime, Rumo, Bjoern, Salzmann, Vladimir N, Strocov, Dmitry, Reznik, Claude, Monney, Frank, Weber

Publikováno v: Nature Communications

Electron-phonon coupling, i.e., the scattering of lattice vibrations by electrons and vice versa, is ubiquitous in solids and can lead to emergent ground states such as superconductivity and charge-density wave order. A broad spectral phonon line sha
