SternGerlach Experiment and Bohm Limit
Abstract
SternGerlach experiment is a paradigm of measurement theory in quantum mechanics. Notwithstanding several analysis given in literature, no clear understanding of the apparent collapse has been given so far. Indeed, one can imagine a SternGerlach device where all environmental effects are removed and ask the question on how the measurement goes on. In this letter we will prove that a the SternGerlach device behaves as a true measurement apparatus, as expected by the Copenaghen interpretation, by the Ehrenfest theorem. In this way we recover, by other means, a limit on the SternGerlach device, given by Bohm, based on scrambling of phases due to a large oscillation frequency.
