Lattice and spin excitations in multiferroic h-YbMnO3
J. Liu, C. Toulouse, P. Rovillain +6
Lattice and spin excitations have been studied by Raman scattering in hexagonal YbMnO3 single crystals. The temperature dependences of the phonon modes show that the E2 mode at 256…
New insights into the phase diagram of the copper oxide superconductors from electronic Raman scattering
A. Sacuto, Y. Gallais, M. Cazayous +3
Mechanism of unconventional superconductivity is still unknown even if more than 25 years have been passed since the discovery of high-Tc cuprate superconductors by J.G. Bednorz an…
Anharmonic suppression of Charge density wave in 2H-NbS
Maxime Leroux, Mathieu Le Tacon, Matteo Calandra +6
The temperature dependence of the phonon spectrum in the superconducting transition metal dichalcogenide 2H-NbS is measured by diffuse and inelastic x-ray scattering. A deep, w…
Electromagnon and phonon excitations in multiferroic TbMnO3
P. Rovillain, J. Liu, M. Cazayous +4
We have performed Raman measurements on TbMnO3 single crystal under magnetic field along the three crystallographic directions. The flip of the spin spiral plane creates an electro…
Exploring the Dark Side of Cuprate Superconductors: s-wave Symmetry of the Pseudogap
S. Sakai, S. Blanc, M. Civelli +12
We reveal the full energy-momentum structure of the pseudogap of underdoped high-Tc cuprate superconductors. Our combined theoretical and experimental analysis explains the spectra…
