Towards mastering terahertz waves ?

Towards mastering terahertz waves ?

The terahertz waves span frequency ranges between the infrared spectrum (used, for example, for night vision) and gigahertz waves (which find their application, among other, in Wi-Fi connections). Terahertz waves allow for the detection of materials that are undetectable at other frequencies. However, the use of these waves is severely limited by the absence of…

Elastic properties revealed by thermal diffuse x-ray scattering

Elastic properties revealed by thermal diffuse x-ray scattering

High-precision measurements of thermal diffuse x-ray scattering revealed that the full elasticity tensor can accurately be obtained in a single crystal diffraction experiment. The new method opens the perspective to determine elastic properties together with crystal structure under the same experimental conditions. The results published in Physical Review Letters show, that absolute values can be…

Electromagnon dispersion probed by inelastic X-ray scattering in LiCrO2

Electromagnon dispersion probed by inelastic X-ray scattering in LiCrO2

Lattice vibrations (phonons) in crystals are typically weakly interacting with the electronic degrees of freedom, such as charge and spin fluctuations. Researchers in the team of Prof. Rüegg (DQMP, University of Geneva and LNS, Paul Scherrer Institute) together with collaborators from the École polytechnique fédérale de Lausanne, Japan and the USA discovered an unexpectedly strong…

Isotope effect in superconducting n-doped SrTiO3

Isotope effect in superconducting n-doped SrTiO3

Strontium titanate is a material with a unique combination of different properties. In its pristine state it is an insulator with a band gap of 3 eV. In the absence of zero-point fluctuations (ZPF) the material would be ferroelectric at low temperatures, and the material can be made ferroelectric by suppressing the ZPF by substituting…
