Quantizing Galilean spacetime: a reconstruction of Maxwell's equations in empty space
Ulf Klein
As was recently shown, non-relativistic quantum theory can be derived by means of a projection method from a continuum of classical solutions for (massive) particles. In this paper…
A reconstruction of quantum theory for spinning particles
Ulf Klein
As part of a probabilistic reconstruction of quantum theory (QT), we show that spin is not a purely quantum mechanical phenomenon, as has long been assumed. Rather, this phenomenon…
A reconstruction of quantum theory for nonspinning particles
Ulf Klein
Within the framework of the individuality interpretation of quantum theory (QT), the basic equations of QT cannot be derived from the basic equations of classical mechanics (CM). T…
From probabilistic mechanics to quantum theory
Ulf Klein
We show that quantum theory (QT) is a substructure of classical probabilistic physics. The central quantity of the classical theory is Hamilton's function, which determines canonic…
From Koopman-von Neumann Theory to Quantum Theory
Ulf Klein
Koopman and von Neumann (KvN) extended the Liouville equation by introducing a phase space function whose physical meaning is unknown. We show that a different $S(…
Is the individuality interpretation of quantum theory wrong ?
Ulf Klein
We analyze the question whether or not quantum theory should be used to describe single particles. Our final result is that a rational basis for such an 'individuality interpretati…
