Quantum-Electrodynamical Processes

1992
In this chapter we will gain some practical abilities in calculating various interesting quantum-electrodynamical processes that are of great importance. Thus the following chapter consists mainly of examples and problems. First, we start by applying the propagator formalism to problems related to electron–positron scattering.

Hyperbolic lattices in circuit quantum electrodynamics

Nature, 2018
After two decades of development, cavity quantum electrodynamics with superconducting circuits has emerged as a rich platform for quantum computation and simulation.

On the Existence of Quantum Electrodynamics

Physical Review Letters, 1988
A partir d'une perspective intuitive du groupe de renormalisation, on explique comment l'«effondrement de la fonction d'onde», dans l'electrodynamique quantique gele, conduit a la renormalisation de la constante de couplage et un point fixe stable ultraviolet en interaction. Un developpement diagrammatique en Nf(le nombre d'especes de fermions) suggere

Superconductor–semiconductor hybrid-circuit quantum electrodynamics

Nature Reviews Physics, 2019
Light–matter interactions at the single-particle level have generally been explored in the context of atomic, molecular and optical physics. Recent advances motivated by quantum information science have made it possible to explore coherent interactions ...

On the Renormalization of Quantum Electrodynamics

Proceedings of the Physical Society. Section A, 1951
The subtraction procedure of Dyson is modified in order to eliminate a certain difficulty in the renormalization programme, namely the so-called `b' divergencies. The conclusions of Dyson concerning the finiteness of the renormalized S matrix are confirmed.

Finite quantum electrodynamics

Physical Review D, 1973
It is shown that the ultraviolet divergences encountered in the lowest-order perturbation calculations of quantum electrodynamics no longer appear if the theory is expanded so as to include the $\ensuremath{\mu}$ meson, a triplet of heavy axial-vector bosons, and two heavy polar-vector bosons, in addition to the electron and photon, and suitably chosen

A simplified quantum electrodynamics

Il Nuovo Cimento, 1962
A version of quantum electrodynamics is presented in which the Heisenberg-picture field equations and commutation relations are exactly the same as in the conventional theory, but in which an indefinite metric is not used, and no subsidiary condition has to be imposed on the state vectors.

Reversibility of Quantum Electrodynamics

Physical Review, 1951
The aim of this paper is to re-establish the reversibility of classical electrodynamics in terms of the "expectation values" given by quantum electrodynamics. The reversibility requirement combined with the charge conjugation necessitates that charged fields should obey certain types of statistics.
