Ultrafast Imaging of Real Space Response Functions

ORAL

Abstract

Understanding the dynamics of spin and charge excitations are critical for the study of correlated materials, such as cuprates. Inelastic X-ray scattering can reveal extensive information related to ultrafast dynamical details about the spin and charge structure factors. To obtain a theoretical understanding, we performed small-cluster exact diagonalization calculations utilizing single-band and three-band Hubbard models with both periodic and open boundary conditions. We demonstrate the ability to track long time behavior; and show that this method can be utilized to study the response dynamics of various materials, such as correlated and chemical systems as well as biological molecules.
