Abstract 

I will first discuss simulating quantum many-body Hamiltonians for one- and two-dimensional cuprate materials with large-scale exact diagonalization and cluster perturbation theory. The charge, spin, and orbital dynamics from these model studies will be presented together with advanced spectroscopies such as inelastic neutron and resonant inelastic x-ray scattering. I will next consider modeling nonequilibrium dynamics revealed by ultrafast spectroscopies in strongly correlated electron-phonon systems. The challenges and plans for performing massive Krylov subspace time evolution combined with quantum cluster methods on the Oak Ridge Leadership Computing Facility also will be addressed.
