Title：Resonant Inelastic X-ray Scattering from correlated electron systems and unconventional High-Tc Superconductors

Time: 10:30, July 12

Place: Meeting Room at No.12 Hall

Speaker: Dr.ZHOU Kejin

Abstract：

Resonant inelastic X-ray scattering (RIXS) [1, 2] is a powerful bulk-sensitive photon-in / photon-out spectroscopic and scattering probe with elemental sensitivity for the electronic structure of condensed matter. It is a unique tool for studying low energy excitations in complex correlated systems, being direct-ly sensitive to charge-, orbital-, spin-, and lattice-degrees of freedom. Dedicated instrumentation for RIXS with ultra-high resolution in energy and momentum spaces has become available thereby enabling charac-terization of collective excitations such as orbitons, magnons and phonons. In this presentation the speaker will give a brief introduction to RIXS technique and focus on the application in correlated electron systems and unconventional high-Tc superconductors [3-9]. The status of the next-generation RIXS facility at Dia-mond Light Source will be also updated during the talk.
