"Ultrafast nonlinear X-ray spectroscopies: lessons from the optical regime" by Jeremy Rouxel

Seminar by Jérémy Rouxel, Laboratoire Hubert Curien, University of California Irvine

Abstract

With the advent of coherent and femtosecond X-ray pulses at free-electron lasers, ultrafast nonlinear X-ray experiments are now feasible. X-rays can offer complementary information to optical experiments thanks to their element sensitivity and atomic spatial resolution. A theoretical framework to describe X-ray and optical signals on the same footing will be presented and experimental realizations will be discussed. These will include transient grating diffraction on Bi4Ge3O12 (BGO) and dichroism of vortex beams from chiral molecules
