The Kramers problem in the energy-diffusion limited regime of very low friction is difficult to deal with analytically because of the repeated recrossings of the barrier that typically occur before an asymptotic rate constant is achieved. Thus, the transmission coefficient of particles over the potential barrier undergoes oscillatory behavior in time before settling into a steady state. Recently, Kohen and Tannor [D. Kohen and D. J. Tannor, J. Chem. Phys. 103, 6013 (1995)] developed a method…

On the generalized Kramers problem with exponential memory friction
Abstract The time-dependent transmission coefficient for the generalized Kramers problem with exponential memory friction has recently been calculated by Kohen and Tannor [D. Kohen, D.J. Tannor, J.
On the generalized Kramers problem with oscillatory memory friction
The time-dependent transmission coefficient for the Kramers problem exhibits different behaviors in different parameter regimes. In the high friction regime it decays monotonically (“nonadiabatic”),
Numerical simulation of transmission coefficient using c-number Langevin equation

Memory-induced acceleration and slowdown of barrier crossing.
This work studies the mean first-passage time τMFP for the barrier crossing of a single massive particle with non-Markovian memory by Langevin simulations in one dimension and finds barrier crossing to be accelerated for intermediate memory time, while for long memoryTime, barrier crossing is slowed down andτMFP increases with τΓ as a power law τM FP∼τΓ2.
Decay of a metastable state induced by a spin bath.
It is shown that, apart from the usual frequency prefactor and its dynamical modification in the spatial diffusion-limited regime, the rate coefficient contains two other factors, a quantum correction to the dynamical factor resulting from quantum transmission and reflection of the particle at the finite barrier and a quantum corrected Arrhenius factor, which incorporates the effect of thermal saturation.

It is shown that the overshooting phenomenon for the passing probability appears in the regime 0<delta<1 and the backflow recrossing over the saddle point is observed, where a nonmonotonous time dependence of the passage probability is detected.

The reactive flux theory for finite barriers is proposed, where the starting point of the trajectories of Brownian particles is removed into a position inside the potential well where the probability distribution can be regarded as an equilibrium one, and the potential barrier is replaced with an equivalent parabolic potential barrier.
Time-dependent barrier passage of one-dimensional fractional damping reactive system
The time-dependent barrier passage of a Brownian particle diffusing in the fractional damping environment is studied by using the reactive flux method. Characteristic quantities such as the rate

The approach developed previously to calculate the decay rate is based on the derivation of an integral equation and enables one to sum up an infinite series in powers of the ratio γU 0 /Tω∼1 contributing to the preexponential factor of the Arrhenius law.
