Light-cone Hamiltonian flow for positronium. The numerical solutions
Elena Gubankova, Gabor Papp
The effective Hamiltonian, as obtained from applying the Hamiltonian flow equations to front form QED, are solved numerically for positronium. Both the exchange and the annihilatio…

Light-cone Hamiltonian flow for positronium
Elena L. Gubankova, Hans-Christian Pauli, Franz J. Wegner +1
The technique of Hamiltonian flow equations is applied to the canonical Hamiltonian of quantum electrodynamics in the front form and 3+1 dimensions. The aim is to generate a bound…
