Fecha de publicación: | 1-ene-2002 | Editor: | Elsevier | Citación: | Physica A 303(1-2): 91-104 (2002) | Resumen: | We have analyzed diffusion in a double well potential driven by a colored non-Gaussian noise. Using a path-integral approach we have obtained a consistent Markovian approximation to the initially non-Markovian problem. Such an approximation allows us to get analytical expressions for the "mean-first-passage-time" that has been tested against extensive numerical simulations. | Descripción: | 14 pages, 4 figures.-- Available online Oct 2, 2001. | Versión del editor: | http://dx.doi.org/10.1016/S0378-4371(01)00435-6 | URI: | http://hdl.handle.net/10261/15300 | DOI: | 10.1016/S0378-4371(01)00435-6 | ISSN: | 0378-4371 |
