Precursor phase with full phonon softening above the charge-density-wave phase transition in -TaSe
Xingchen Shen, Rolf Heid, Roland Hott +8
Research on charge-density-wave (CDW) ordered transition-metal dichalcogenides continues to unravel new states of quantum matter correlated to the intertwined lattice and electroni…
Three-dimensional Fermi surface of 2H-NbSe - Implications for the mechanism of charge density waves
F. Weber, R. Hott, R. Heid +4
We investigate the three-dimensional electronic structure of the seminal charge-density-wave (CDW) material 2H-NbSe by soft x-ray angle-resolved photoelectron spectroscopy and…
Cuprate High Temperature Superconductors
Roland Hott, Thomas Wolf
Short review of the topical comprehension of Cuprate High-Temperature Superconductors, featuring structural and metallurgical aspects that optimize their superconducting properties…
Review on Superconducting Materials
Roland Hott, Reinhold Kleiner, Thomas Wolf +1
Short review of the topical comprehension of the superconductor materials classes Cuprate High-Temperature Superconductors, other oxide superconductors, Iron-based Superconductors,…
Optic phonons and the soft mode in 2H-NbSe2
F. Weber, R. Hott, R. Heid +6
We present an investigation of the lattice dynamics of the charge-density-wave compound 2H-NbSe2. We analyze the precise nature of the wave vector dependent electron-phonon couplin…
Electron-Phonon Coupling and the Soft Phonon Mode in TiSe
F. Weber, S. Rosenkranz, J. -P. Castellan +6
We report high-resolution inelastic x-ray measurements of the soft phonon mode in the charge-density-wave compound TiSe. We observe a complete softening of a transverse optic p…
