We summarize our recent efforts in investigating the charge–density-wave (CDW) state of the rare-earth tri-tellurides RTe 3 by means of infrared and Raman techniques. We identify the CDW gap, as order parameter of the broken-symmetry ground state,

We report on our recent optical measurements of the Pr tri-telluride charge-density-wave system. Our data, collected over an extremely broad spectral range, allow us to observe both the Drude component and the single-particle peak, ascribed to the co

Sm 1− x La x S for x more than a few percents are metals at ambient conditions. At low temperature and high pressure they develop a small gap in the order of some meV and become semiconductors or insulators. This has been interpreted as a manifesta

Epitaxially grown V2O3(0001) thin films have been prepared with different surface terminations, as evidenced by atomically resolved scanning tunnelling microscopy and high-resolution electron energy loss spectroscopy (HREELS) phonon spectra. The spec

We report a neutron diffraction study of the magnetic phase transitions in the charge-density-wave (CDW) TbTe$_3$ compound. We discover that in the paramagnetic phase there are strong 2D-like magnetic correlations, consistent with the pronounced anis

We investigate the optical conductivity with light polarized along the in-plane orthorhombic a and b axes of Ba(Fe1−xCox)2As2 for x=0 and 2.5% under uniaxial pressure across their structural and magnetic transitions. The charge dynamics at low freq

We report on a thorough optical investigation over a broad spectral range and as a function of temperature of the charge dynamics in Ba(CoxFe1- x)2As2 compounds for Co-doping ranging between 0 and 18%. For the parent compound as well as for x=0.025,

We report an x-ray diffraction study on the charge-density-wave CDW LaTe3 and CeTe3 compounds as a function of pressure. We extract the lattice constants and the CDW modulation wave vector. We observe that the intensity of the CDW satellite peaks ten
