Variational Quantum Electrodynamics [PDF]
A variational method is discussed, based on the principle of minimal variance. The method seems to be suited for gauge interacting fermions, and the simple case of quantum electrodynamics is discussed in detail. The issue of renormalization is addressed,

Non-Equilibrium Quantum Electrodynamics [PDF]
We employ the influence functional technique to trace out the photonic contribution from full quantum electrodynamics. The reduced density matrix propagator for the spinor field is then constructed.

On the Emergence of the Coulomb Forces in Quantum Electrodynamics [PDF]
A simple transformation of field variables eliminates Coulomb forces from the theory of quantum electrodynamics. This suggests that Coulomb forces may be an emergent phenomenon rather than being fundamental.

Quantum gravitational contributions to quantum electrodynamics [PDF]
Quantum electrodynamics describes the interactions of electrons and photons. Electric charge (the gauge coupling constant) is energy dependent, and there is a previous claim that charge is affected by gravity (described by general relativity) with the ...

Nonperturbative waveguide quantum electrodynamics
Understanding physical properties of quantum emitters strongly interacting with quantized electromagnetic modes is one of the primary goals in the emergent field of waveguide quantum electrodynamics (QED).

On higher order estimates in quantum electrodynamics [PDF]
We propose a new method to derive certain higher order estimates in quantum electrodynamics. Our method is particularly convenient in the application to the non-local semi-relativistic models of quantum electrodynamics as it avoids the use of iterated commutator expansions.

On the Renormalization in Quantum Electrodynamics [PDF]
The new renonnalization procedure in quantum electrodynamics is presented in this paper. With this procedure, the finite S-matrix can be automatically obtained by· use of the modified commutation relations and propagation functions and, therefore, without introducing the counter tenns of mass- and charge-types.

Beables for Quantum Electrodynamics [PDF]
We show that it is possible to obtain a realistic and deterministic model, based on a previous work of John Bell, which reproduces the experimental predictions of the orthodox interpretation of quantum electrodynamics.

Quantum electrodynamics with magnetic textures
Coherent exchange between photons and different matter excitations (like qubits, acoustic surface waves or spins) allows for the entanglement of light and matter and provides a toolbox for performing fundamental quantum physics.
