Crystal Lattice Dynamics Measured Using Particle Scattering

The development of next generation technologies is dependent upon exploiting the connection between a material's form and function at the atomic and molecular scales. In this talk, I'll present the theory of lattice vibrations and the significance of lattice vibrations in the phase stability of technologically relevant materials.  I'll review the use of elementary particles as tools for studying crystalline, with a focus on atomic-scale structure and dynamics.  Results will be presented from recent research of the phase stability of VO2, V2O3, and TiO2, as well as magnon-phonon coupling in magnetocaloric materials.
