Radiation damage in metals

Research

	A one page introduction to our work. A non-technical introduction for general readers.		Radiation damage cascades. The goal of our work is adding to the understanding of non-adiabatic processes in radiation damage. We have been looking at low energy cascades in the Ehrenfest approximation ( classical ions and quantum mechanical electrons ) for systems up to 32k atoms.
	Electronic damping We model the evolution of the electronic subsystem in response to a time-dependent Hamiltonian with explicit dependence on the ionic configuration, and so can measure the irreversible transfer of energy into the electronic subsystem.		Sputtering simulations Sputtering has previously been simulated using classical molecular dynamics. It is an open question how the ionic dynamics are affected by charge transfer. We have been using a time-dependent self-consistent tight-binding framework to find out more.
