Path Integral Solution of the Kramers Problem
(American Physical Society, 1996-12-30)
An iterative method to generate a discrete path integral solution of the Kramers problem is presented. It is based on a straightforward derivation of the functional formalism from the underlying Langevin equations. The ...

Expansion for the moments of a nonlinear stochastic model
(American Physical Society, 1996-10-14)
We present a procedure to systematically evaluate all the moments of the Fokker-Planck equation by expanding them in a power series in a given function of t. The expansion coefficients are easily determined in terms of ...

External-field effects on molecular electronic transitions in charge-transfer systems
(American Physical Society, 1998)
We investigate strong-external-field effects on optical transitions between electronic states of charge-transfer systems in condensed media. We will use as a model a two-level system coupled to a dissipative medium driven ...

Dynamics of single and multiple Zener transitions
(American Institute of Physics Publising LLC, 1992)
The probability of remaning in a given state is evaluated for a two-level system that can cross repeatedly and periodically as a function of a control parameter. The possibility of multiple Zener transitions between the ...
