The lattice spinor QED Hamiltonian critique of the continuous space approach
A.V. Sidorov, L.G. Zastavenko · CERN Document Server (European Organization for Nuclear Research) · 1993
We give the irreproachable, from the point of view of gauge invariance, derivation of the lattice spinor QED Hamiltonian. Our QED Hamiltonian is manifestly gauge invariant. We point out important defects of the continuous space formulation of the QED that make, in our opinion, the lattice QED obviously preferable to the continuous space QED. We state that it is impossible to give a continuous space QED formulation which is compatible with the condition of gauge invariance. 17 refs. 17 refs. Submitted to Phys. Scr.
