A Causal and Local Interpretation of Experimental Realization of Wheeler's Delayed-choice Gedanken Experiment.

Recently the experimental group of A. Aspect published a very interesting experimental realization of the well known Wheeler's delayed-choice Gedanken Experiment. In the paper the authors refer to the usual, non causal linear explanation of the experiment. In the present work we show how it is possible, and furthermore desirable, to explain the same experiment in terms of the modern local causal and nonlinear quantum theory, inspired in the work of the great physicist Louis de Broglie. In this way we are able to get rid of the mysteries and of the weird features of the orthodox interpretation, like retractions in time, and therefore recover causality and rationality once more.
