Time-dependent barrier passage of two-dimensional non-Ohmic damping system.
The time-dependent barrier passage of two-dimensional non-Ohmic damping system is studied in the framework of statistical Langevin reactive dynamics. The stationary transmission coefficient is found to be a nonmonotonic function of the exponent delta which reveals an intrinsic effect of the friction's non-Markovian character on the two-dimensional reactive process; the coupling between nonreactive and reactive modes results in an optimal path for the reactant in all cases of non-Ohmic friction. A big net flux resulted from the less barrier recrossing behavior in the two-dimensional non-Ohmic friction case.
