Some remarks on Dirac's hole theory versus quantum field theory
Dan Solomon
Dirac's hole theory and quantum field theory are generally considered to be equivalent to each other. However, it has recently been shown that this is not necessarily the case. In…

No limit on the energy extracted from a Dirac quantum state
Dan Solomon
When a Dirac quantum state interacts with an applied electric field the energy of the quantum state changes. It is generally assumed that there is a maximum limit on the amount of…

Gauge invariance and the Dirac free field energy
Dan Solomon
Dirac field theory is assumed to be gauge invariant. However it is well known that a calculation of the polarization tensor yields a non-gauge invariant result. The reason for this…
