The problem of gauge invariance and the functional Schroedinger approach
Dan Solomon
Quantum field theory is assumed to be gauge invariant. However it is well known that when certain quantities, such as the vacuum current, are calculated the results are not gauge i…
Another look at the problem of gauge invariance in QFT
Dan Solomon
It is generally assumed that quantum field theory (QFT) is gauge invariant. However it is well known that non-gauge invariant terms appear in various calculations. This problem was…
A new look at the problem of gauge invariance in quantum field theory
Dan Solomon
Quantum field theory is assumed to be gauge invariant. However it is well known that when certain quantities are calculated using perturbation theory the results are not gauge inva…
The Heisenberg versus the Schroedinger picture and the problem of gauge invariance
Dan Solomon
It is generally assumed that quantum field theory (QFT) is gauge invariant. However it is well known that non-gauge invariant terms appear in various calculations. This problem was…
On the energy of physical states in QED in the convariant gauge
Dan Solomon
In quantum field theory it is generally assumed that there is a lower bound to the energy of a quantum state. Here, it will be shown that there is no lower bound to the energy of p…
Space-like energy momentum in quantum electrodynamics
Dan Solomon
A common assumption in quantum field theory is that the energy-momentum 4-vector of any quantum state must be time-like. However it has been recently shown [4] that this is not the…
Quantum states with less energy than the vacuum in Dirac Hole Theory
Dan Solomon
In Dirac's hole theory the vacuum state is generally believed to be the state of minimum energy. However it has recently been shown that this is not the case. In [1] it was shown t…
Some new results concerning the QFT vacuum in the Heisenberg picture
Dan Solomon
In has been recently shown [1] that in Dirac's hole theory the vacuum state is not the minimum energy state but that there exist quantum states with less energy than that of the va…
