简介: |
Continuum field theories have been of continuous great interest in
modeling and understanding complex phenomena during materials
growth and processing. Traditionally such approaches are featured
by the description of long wavelength or coarse-graining scale of a
system, while typical material phenomena involve a variety of spatial
and temporal scales that interact and couple. The recently developed
phase-field-crystal (PFC) methods can overcome such limit of
conventional approaches via incorporating microscopic crystalline
details into mesoscopic continuum theory. In this talk I will discuss
some recent advances in the development of the PFC methodology
that bridges different scales, and also its applications to the modeling
of some out-of-equilibrium solidification systems that are of large
interest, including nanostructure self-assembly in strained solid
films, alloy phase separation, dynamics of liquid-solid interface and
topological defects, as well as an important lattice pinning effect
during materials evolution due to the coupling between micro and
meso spatial scales.
A short biosketch:
Dr. Zhi-Feng Huang received his PhD degree in Physics from TsingHua
University, China, and has worked at Cologne University of Germany,
University of Toronto, Florida State University, and McGill University
before joining Wayne State University in 2006. Currently he is an
associate professor of Physics at Wayne State. He was a recipient
of the US National Science Foundation CAREER Award in 2009.
