Bio: Dr. Yi-De Chuang is a staff scientist at the Advanced Light Source (ALS), Lawrence Berkeley National Laboratory. He completed his undergraduate study in National Taiwan University. He received a PhD degree in Physics from the University of Colorado at Boulder in 2001. He joined the ALS as a postdoctoral researcher in 2002. Since then, he has been staying at the ALS for pursuing his scientific career. He became a physicist scientist in 2006 and a staff scientist in 2015. His research interest is using soft x-ray spectroscopic techniques, such as time-resolved and static resonant elastic/inelastic x-ray scattering, to study the electronic structure of correlated materials. Dr. Chuang has extensive experience in developing novel synchrotron instrumentation such as x-ray beamlines and spectrometers.
Abstract:
Resonant inelastic x-ray scattering (RIXS) spectroscopy has emerged as a powerful synchrotron-based technique for studying the electronic structure of correlated materials. Complementary to the angle-resolved photoemission (ARPES) and inelastic neutron scattering (INS), RIXS can offer a very high spectral resolution and a large energy transfer range to measure the two-particle spectral response in lattice, charge, spin, and orbital degrees of freedom. In this talk, I will give an overview of this technique and its potential in addressing key questions we face in cuprate superconductivity. I will also discuss the novel optical schemes that will greatly enhance the spectral resolution and throughput in 4th generation light source.
