Projects:
Ph.D. (see thesis), Work with Harvey
Gould and Bill Klein,
Department
of Physics, Clark University
- develop molecular
dynamics simulation programs for
the Burridge-Knopoff spring-block model;
- develop computer
simulation programs for cellular
automata models such as the Olami-Feder-Christensen and the
Rundle-Jackson-Brown;
- investigate the
mean-field behavior of the Burridge-Knopoff
model with various long range interactions;
- verify the mean-field
behavior of the long-range
Olami-Feder-Christensen model predicted by Klein and Rundle et
al.
- look for scaling in
the long range
OFC model;
- study the phase
transition of the long range
OFC model induced by the loading velocity.
Microstructure Evolution
of Liquid Metals
during Ultra-fast Solidification (09/1997 ~ 07/1999)
Master thesis, work with Zhengang
Zhu and Changsong Liu,
Institute
of
Solid State Physics , Chinese
Academy of Sciences,
- developed molecular
dynamics simulation programs (NVT and
NPH) for liquid metals and semiconductors using more realistic
multi-body interaction potentials such as EAM and Tersoff;
- developed microscopic
structure analysis programs to
identify clusters in liquids, crystals and glasses including
both traditional methods such as radial distribution function
and angular distribution function, and nontraditional methods
such as pair analysis technique of Honeyccut and Anderson and
bond-orientational order analysis technique of Nelson et al.;
- studied the
microstructure evolution
of some liquid metals
during the crystallization and glass formation under ultra-fast quench.
Other mini-projects
done for practice:
- located the critical
point of the gas-liquid transition
of L-J system under an external field by finite size scaling
technique and MD and
MC techniques
- numerical
simulation
of the Langevin equation of the Ising
model.
