Research interest: Nonequilibrium statistical
thermodynamics of dissipative many-body systems
(e.g. granular matter,
earthquakes, dislocations, etc…).
Current problems:
1. The nature of jamming transition: rheology, dynamical heterogeneity, dynamic criticality, etc. (see some results 1. 2. 3.).
2. The origin of statistical laws in seismology: Gutenberg-Richter law, Omori law, recurrence time distribution, etc.
3. Earthquake mechanics (e.g. Relation between rupture propagation dynamics and the friction law).
Past
problems:
* Heat conduction in one-dimensional lattices
* The second law of nonequilibrium thermodynamics (as well as the 0th law).
* Atomistic mechanism of shock compression of solids (Phys. Rev. Lett. 92, 015503
(2004); Phys. Rev.
Lett. 93, 085501 (2004).)
* Dynamics of dislocation pinning in crystalline materials (Phys. Rev. B 77, 064108 (2008); Phys. Rev. B 74, 020102(R) (2006); Phys. Rev. B 72, 094105 (2005))
