We investigate the low-temperature relaxation dynamics toward a nonequilibrium steady state in a tilted asymmetric periodic potential based on the WKB analysis and the numerical diagonalization of the Fokker-Planck operator. Due to the tilting, th...
We investigate asymptotic decay phenomena towards the nonequilibrium steady state of the thermal diffusion in a periodic potential in the presence of a constant external force. The parameter dependence of the decay rate is revealed by investigatin...

We explore the role of an intermediate state (phase) in homogeneous nucleation by examining the decay process through a double-humped potential barrier. We analyze the one-dimensional Fokker-Planck (FP) equations with the fourth- and sixth-order L...
