Broken Time Translation Symmetry as a model for Quantum State Reduction
Authors: Jasper van Wezel

MIght interest, yes. But the field of quantum theory is a sort of Babylonia.

Let us reread Fuchs and Peres (Physics Today, 2000):
"Contrary to those desires, quantum theory does not describe physical 
reality.
What it does is provide an algorithm for computing probabilities for the 
macroscopic
events ("detector clicks") that are the consequences of our experimental 
interventions.
This strict definition of the scope of quantum theory is the only 
interpretation ever needed,
whether by experimenters or theorists."

Now, if QT does *not* describe *reality*, or *physical" reality, it makes 
little sense to
try to transform QT into an ontological theory. Mainly because its Procustean 
formalism 
does not describe physical reality, the ontological reality, the standing-
alone reality. 

I had the chance, in the '70s, of attending a conference in which one of the 
two (or
maybe three)  guys who created the quantum formalism made, more or less, 
the same point.
