  • Probing emerging excitations in solids with Resonant Inelastic X-ray Scattering (RIXS)
    LQMEC Synergy com Prof. Tulio Costa Rizuti da Rocha (Ipê Beamline, LNLS) 
    16/12, 6ª feira, 15h. [Presencial] Ed. Principal, Auditório Giuseppe Ochialini.


Emerging excitations play a central role in understanding the macroscopic properties of quantum materials. The most notable example is the high-temperature superconductors, for which various collective modes such as phonons, polarons, plasmons and magnons might contribute or compete with the formation of Cooper pairs that determine the superconducting state. The dispersion relation of the elementary excitations, i.e., the dependence of their energy on the wave-vector, is one of the most fundamental properties of a quantum many-body system. In this talk, I will show the principles of the resonant inelastic X-ray scattering (RIXS), a technique that can directly probe the momentum resolved excitation spectrum of transition metal compounds. 

Particularly, I will show recent results from the investigation of an unusual orbital ordering in CuSb2O6 and the search of collective orbital excitations. Additionally, I will also present details about the RIXS instrument under construction at the IPE beamline of the Sirius synchrotron light source at LNLS/CNPEM.
