| contents | Tunneling and the Vacuum Zero-Point Radiation H. M. França G. G. Gomes R. L. Parra Física, Astronomía y Matemáticas Zero Tunneling point fluctuations Foundations of quantum mechanics We make a brief review of the Kramers escape rate theory for the probabilistic motion of a particle in apotential well U(x), and under the influence of classical fluctuation forces. The Kramers theory is extended inorder to take into account the action of the thermal and zero-point random electromagnetic fields on a chargedparticle. The result is physically relevant because we get a non null escape rate over the potential barrier at lowtemperatures (T ! 0). It is found that, even if the mean energy is much smaller than the barrier height, theclassical particle can escape from the potential well due to the action of the zero-point fluctuating fields. Thesestochastic effects can be used to give a classical interpretation to some quantum tunneling phenomena. Relevantexperimental data are used to illustrate the theoretical results. 2007 artículo científico 0103-9733 https://www.redalyc.org/articulo.oa?id=46437106 en http://www.redalyc.org/revista.oa?id=464 Brazilian Journal of Physics application/pdf Sociedade Brasileira de Física Brazilian Journal of Physics (Brasil) Num.1A Vol.37 |
