Differences between the trajectory representation and Copenhagen regarding the past and present in quantum theory
arXiv:quant-ph/0307090
Abstract
We examine certain pasts and presents in the classically forbidden region. We show that for a given past the trajectory representation does not permit some presents while the Copenhagen predicts a finite probability for these presents to exist. This suggests another gedanken experiment to invalidate either Copenhagen or the trajectory representation.
