Negative energy density for a Dirac-Maxwell field
Dan Solomon
It is well known that there can be negative energy densities in quantum field theory. Most of the work done in this area has involved free non-interacting systems. In this paper we…
Quantum states with a space-like energy momentum
Dan Solomon
A common assumption in quantum field theory is that the energy-momentum 4-vector of any quantum state must be timelike. It will be proven that this is not the case for a Dirac-Maxw…
Gauge invariance and the vacuum state
Dan Solomon
Quantum field theory is assumed to be gauge invariant. It is shown that for a Dirac field the assumption of gauge invariance impacts on the way the vacuum state is defined. It is s…
Mathematical Inconsistencies in Dirac Field Theory
Dan Solomon
If a mathematical theory contains incompatible postulates then it is likely that the theory will produce theorems or results that are contradictory. It will be shown that this is t…
