We just finished a study demonstrating a way to use time-resolved RIXS to measure the collective exctiations of quantum materials, in this instance CDW-ordered La2-xBaxCuO4 (LBCO). The idea is to weakly perturb the system with a pump pulse and then measure the time evolution of the order parameter, which encodes the collective excitations of the […]
We just finished our first Free Electron Laser experiment, using the SXR endstation during Run 15 of the Linac Coherent Light Source. The goal was to study the collective modes of the stripe phase in La2-xBaxCuO4. SLAC Facebook post here.
We did our first experiment on qRIXS, the world’s first fully angle-resolved soft RIXS spectrometer, which is under development at the Advanced Light Source. This thing will open up a new approach to studying valence band excitations in materials. Find out more.
