Ultrafast processes at high fields and high pressures: Towards atomic-scale visualization and control of materials dynamics

One of the great challenges of materials science is to go beyond simple understanding  of the atomic-scale processes that determine materials functionality, and to seek methods for engineering and directing these processes.  In this talk I will describe several related efforts within our group towards this end, focused on exploring how materials transform, and making use of a broad class of x-ray spectroscopic and scattering techniques coupled with new methods for manipulating these materials.  These include recent measurements of the speed limits underlying nanoscale transformations in superionic materials, terahertz-driven polarization dynamics in ferroelectric and multiferroic thin films, and shock-driven solid-solid phase transitions in nanomaterials.  Together these measurements enable extraction of the atomic-scale mechanisms underlying these transformations, and identify pathways for manipulating these materials on ultrafast time-scales.
