Seminar - Modeling the solidification, growth and properties of multiferroic polycrystalline materials by Prof. Ken Elder
Date: 02 April 2014 (Wednesday)
Time: 11:00 am – 11:50 am
Venue:EF305, The Hong Kong Polytechnic University
In this talk Professor Elder would like to discuss the development of a method that can model the solidification of polycrystalline multiferroic material. It will be shown that the model naturally incorporates magnetostriction, piezoelectric effect and the strongly anisotropic ordering of the electromagnetic dipole fields. Furthermore the model can be used to characterize the mechanical and electromagnetic properties of such polycrystalline materials.
Professor Ken Elder is a theoretical condensed matter physicist who studies non-equilibrium pattern formation in materials physics. His work has included studies of spinodal decomposition, Ostwald ripening, eutectic solidification, order/disorder transitions, Rayleigh-Benard convection, flame front propagation, explosive crystallization, the decay of supercurrents in superconducting rings, the motion of charge density waves, the absorption of liquids by random media (or imbibition) and phase separation in fluids. More recently he and collaborators developed a method coined "Phase Field Crystal" modeling to study elastic and plastic deformation in a wide variety of non-equilibrium phenomena. Dr. Elder received his PhD from the University of Toronto and held research appointments at McGill University and the University of Illinois at Urbana Champaign. He is currently a professor of physics at Oakland University.
