Arrival Time Distributions of Spin-1/2 Particles
Abstract
The arrival time statistics of spin-1/2 particles governed by Pauli's equation, and defined by their Bohmian trajectories, show unexpected and very well articulated features. Comparison with other proposed statistics of arrival times that arise from either the usual (convective) quantum flux or from semiclassical considerations suggest testing the notable deviations in an arrival time experiment, thereby probing the predictive power of Bohmian trajectories. The suggested experiment, including the preparation of the wave functions, could be done with present-day experimental technology.
Thanks, I had a look at Maudlin's book. It seems the distinction between signaling and causation is that there might be some kind of nonlocal causation that we can't control and so can't use to send a signal. Local causation is defined as in Bell's Theory of Local Beables, as…
