Low dimension dynamics
in the
The
Einstein-Podolsky-Rosen-Bohm (EPRB) experiment performed with random
variable
and spatially separated analyzers is a milestone test in the
controversy
between Objective Local Theories (OLT) and Quantum Mechanics (QM). Only
a few
OLT are still possible. Some of the surviving OLT (specifically, the so
called
non-ergodic theories) would be undetectable in the averaged statistical
values,
but they may leave their trace in the time dynamics. For, while QM
predicts
random processes, the OLT of this kind predict the existence of
regularities
that may be revealed as a low dimensional object in the phase space. We
perform
a numerical analysis of the time-resolved data recorded in that
experiment to
unveil any hypothetical low dimensional dynamics that may be present.
We find
no consistent indication of such dynamics except for one data file, the
longest
of all in the real time. The possible causes of these dynamics are
discussed.
