| Research Abstract |
1. Dynamic Extension of the Tsallis Statistics :
Langevin dynamics for Tsallis statics is given. It is applied to study anamolous Brownian motion and Kramers Problem.
2. Langevin Equation and Entropy Production :
Entropy production rate is formulated for both the dynamical systems (deterministic) and stochastic systems. We considered the Gulton staircase problem, which gathered a lot of attention recently.
3. Temperature Control and Simulated Annealing :
Control of temperature is the most important factor in the simulated annealing method. We developed a new theory, in which we maximize the expected value of energy under the constraint that the distribution function satifies the Fokker-Planck equation or the master equation. This new method is applied to the protein folding problem.
