Descripción de la difracción de partículas mediante trayectorias cuánticas bohmianas.

Ángel S. Sanz, Salvador Miret- Artés


The trajectory-based formalism of Bohmian mechanics constitutes an alternative (but equivalent at a predictive level) approach to the standard formulation of quantum mechanics. Here we show the advantages of this formalism in providing both an accurate description and a novel interpretation when it is applied to different phenomena of interest in elastic particle scattering, such as diffraction by “hard” and “soft” slits, and quantum vortical dynamics due to the presence of single adsorbates. These problems illustrate fairly well how quantum trajectories are able to satisfactorily reproduce the main features of real scattering experiments as well as to provide a causal insight of the underlying dynamics
