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

Uniaxial strain-induced phase transition in the 2D topological semimetal IrTe2

Autor: Christopher W. Nicholson, Maxime Rumo, Aki Pulkkinen, Geoffroy Kremer, Björn Salzmann, Marie-Laure Mottas, Baptiste Hildebrand, Thomas Jaouen, Timur K. Kim, Saumya Mukherjee, KeYuan Ma, Matthias Muntwiler, Fabian O. von Rohr, Cephise Cacho, Claude Monney

Publikováno v: Communications Materials, Vol 2, Iss 1, Pp 1-8 (2021)

Uniaxial strain is a powerful approach to tune material properties and select between nearly degenerate phases. Here, uniaxial strain is used to stabilize the elusive 6×1 charge ordered ground state of IrTe2, revealing insights into its electronic s

Publikováno v: PLoS ONE, Vol 8, Iss 11, p e78773 (2013)

BACKGROUND: Skin is the largest human neuroendocrine organ and hosts the second most numerous microbial population but the interaction of skin neuropeptides with the microflora has never been investigated. We studied the effect of Substance P (SP), a

Black phosphorus is a quasi-two-dimensional layered semiconductor with a narrow direct band gap of 0.3 eV. A giant surface Stark effect can be produced by the potassium doping of black phosphorus, leading to a semiconductor to semimetal phase transit

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

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

This paper shows how the detailed dispersion of the giant Rashba split surface states in the ferroelectric \ensuremath{\alpha}--GeTe(111) can be resolved by static ARPES and surface potassium doping. The authors further confirm the Rashba mechanism f
