The Condensed Matter Division investigates the dynamics of solids using time dependent techniques. Tabletop and accelerator-based light sources, covering the whole electromagnetic spectrum from the THz to the hard X-rays, measure the structural dynamics of electrons, spins and atomic lattices in quantum condensed matter. Several independent research groups are exploring alternative techniques, including nanoelectronic dynamics measured with a picosecond STM, attosecond timescale X-ray spectroscopies of solids, and theory of ultrafast quantum many body physics.
