We extend to quantized fields the phase-space formalism previously developed for one-
particle relativistic quantum theory. An integral transform is derived which extends an …

We show that quadratic spaces are a fundamental clue to understand the structure of
theoretical physics. Classical Physics is embedded within a 5-D flat quadratic space, 3 …

We develop a trajectory construction of solutions to the massless wave equation in n+ 1
dimensions and hence show that the quantum state of a massive relativistic system in 3+ 1 …

We show that turning on the interaction of relativistic spinless particles with the vacuum of
relativistic quantum mechanics (RQM) leads to the replacement of the Klein-Gordon …

We show that the real massive Klein-Gordon theory admits a description in terms of states
on various timelike hypersurfaces and amplitudes associated with regions bounded by …

The conserved probability densities (attributed to the conserved currents derived from
relativistic wave equations) should be nonnegative and the integral of them over an entire …

Quantum field theory is the traditional solution to the problems inherent in melding quantum
mechanics with special relativity. However, it has also long been known that an alternative …

In physics, experiments ultimately inform us about what constitutes a good theoretical model
of any physical concept: physical space should be no exception. The best picture of physical …
