Inelastic light scattering
Web28 feb. 2014 · Recent resonant inelastic X-ray scattering (RIXS) experiments in hole-doped cuprates have purported to measure high-energy collective spin excitations that persist well into the overdoped regime and bear a striking resemblance to those found in the parent compound, challenging the perception that spin excitations should weaken with … WebIf light interacts with matter without changing its frequency, the process is called elastic scattering because the photons change only their direction and not their energy. The …

Web27 aug. 2024 · Clusters of single spins form the relevant spin entities in the formation of long-range magnetic order in spin cluster Mott insulators. Such type of spin order bears resemblance to molecular crystals, and we therefore may expect a prototypical spin wave spectrum which can be divided into low-energy external and high-energy internal cluster … WebElastic scattering means that the wavelength of the scattered light is not changed, apart from a possible Doppler shift due to the movement. That implies that the inner …
WebInelastic light scattering techniques includes Brillouin and Raman scattering (Loudon 1975). Both techniques analyze the light scattered by a sample with a frequency change. The frequency change relates to the interactions of the photons associated with the incident light with the excitations present in the sample. Web11 apr. 2024 · We study the scattering rate of light inelastic DM with electrons in the XENON1T experiment and with nuclei in the XENON1T, CRESST-III, CDEX-1B and DarkSide-50 experiments. We resolve the recent ...
WebFor example, our low temperature, pressure-dependent inelastic light scattering studies of the critical ('soft') mode in 1T-TiSe 2 indicate that lattice compression leads to quantum … WebWe demonstrate a new design for a light-scattering microscope that is convenient to use and that allows simultaneous imaging and light scattering. The design is motivated by the growing use of thermal fluctuations to probe the viscoelastic properties of complex inhomogeneous environments. We demonstrate measurements of an optically …
