Alternative route to charge density wave formation in multiband systems
H. -M. Eiter, M. Lavagnini, R. Hackl +7
Charge and spin density waves, periodic modulations of the electron and magnetization densities, respectively, are among the most abundant and non-trivial low-temperature ordered p…
High pressure phases of crystalline tellurium
Carlo Marini, Daniele Chermisi, Michela Lavagnini +4
A study of high pressure solid Te was carried out at room temperature using Raman spectroscopy and Density Functional Theory (DFT) calculations. The analysis of the P-dependence of…
Raman scattering evidence for a cascade-like evolution of the charge-density-wave collective amplitude mode
M. Lavagnini, H. -M. Eiter, L. Tassini +6
The two-dimensional rare-earth tri-tellurides undergo a unidirectional charge-density-wave (CDW) transition at high temperature and, for the heaviest members of the series, a bidir…
Pressure dependence of the single particle excitation in the charge-density-wave CeTe system
M. Lavagnini, A. Sacchetti, C. Marini +8
We present new data on the pressure dependence at 300 K of the optical reflectivity of CeTe, which undergoes a charge-density-wave (CDW) phase transition well above room temper…
Pressure-induced quenching of the charge-density-wave state observed by x-ray diffraction
A. Sacchetti, C. L. Condron, S. N. Gvasaliya +11
We report an x-ray diffraction study on the charge-density-wave (CDW) LaTe and CeTe compounds as a function of pressure. We extract the lattice constants and the CDW modula…
Evidence for coupling between collective state and phonons in two-dimensional charge-density-wave systems
M. Lavagnini, M. Baldini, A. Sacchetti +8
We report on a Raman scattering investigation of the charge-density-wave (CDW), quasi two-dimensional rare-earth tri-tellurides Te (= La, Ce, Pr, Nd, Sm, Gd and Dy) at am…
