One of the main activites of the POLIMIX group is the investigation of Strongly Correlated Systems and other Quantum Materials using Resonant Inelastic X-ray Scattering and other synchrotron-based tehcniques.<\/p>\n <\/div>\n <\/div>\n <\/div>\n <\/div>\n <\/div>\n <\/div>\n <\/div>\n

Our main tool is Resonant Inelastic X-ray Scattering, an innovative X-ray tehcnique whose technical development and scientific exploration in the last 15 years carry the name of our group.<\/p>\n

The first modern RIXS spectrometers were built here at the Physics Department, and then mounted at ESRF and Swiss Light Source. After that, our group took an active role in the design of the ERIXS spectrometer at the ESRF, which started\n operation in 2015, and hRIXS, the new hRIXS spectrometer of the European-XFEL, the first soft x-ray RIXS intruments for pump-probe experiments.<\/p>\n

In the last 5 years, many more RIXS spectrometers were built in state-of-the-art synchrotron in the United States, England, Sweden, and Germany.<\/p>\n

RIXS is a photon-in photon-out technique which inherits the characteristics of two different families of x-ray tehcniques: spectroscopy and diffraction. The process is similar to the more-common (non-resonant) IXS and Inelastic Neutron\n Scattering (INS): we shine our materials with monochromatic x-rays, and by analysing the energy and direction of the scattered photons we can retrieve the energy and momentum of the excitations created in the material during the\n scattering event.<\/p>\n

However, differently from IXS and INS, we tune the photon energy to a core-absorption edge, such as the L-edge of transition metals, the K-edge of light elements, or the M-edge of rare earths. This resonant character brings tremendous\n advantages:<\/p>\n
