Algebraic Structures in the Coupling of Gravity to Gauge Theories
, 2020 This article is an extension of the author's second master thesis [1]. It aims to introduce to the theory of perturbatively quantized General Relativity coupled to Spinor Electrodynamics, provide the results thereof and set the notation to serve as a ...

Variational quantum electrodynamics [PDF]
Physical Review D, 2014 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, and the renormalized propagators are shown to be the solution of a set of finite integral equations.

The Importance of Boundary Conditions in Quantum Mechanics [PDF]
, 2003 We discuss the role of boundary conditions in determining the physical content of the solutions of the Schrodinger equation. We study the standing-wave, the ``in,'' the ``out,'' and the purely outgoing boundary conditions. As well, we rephrase Feynman's $

Run-away solutions in relativistic spin 1/2 quantum electrodynamics [PDF]
, 1997 The existence of run-away solutions in classical and non-relativistic quantum electrodynamics is reviewed. It is shown that the less singular high energy behavior of relativistic spin 1/2 quantum electrodynamics precludes an analogous behavior in that ...

Phenomenological Quantum-Electrodynamics
Physical Review, 1948 The quantization of the pure radiation field in a uniformly moving refractive medium is carried through both in the Hamiltonian and in the symmetrical four-dimensional form. The total energy and momentum are diagonalized. For a medium velocity larger than $\frac{c}{n}$ there occur photons with negative energy.

Offshell quantum electrodynamics
Journal of Physics: Conference Series, 2013 More than twenty years have passed since the threads of the `proper time formalism' in covariant classical and quantum mechanics were brought together to construct a canonical formalism for the relativistic mechanics of many particles. Drawing on the work of Fock, Stueckelberg, Nambu, Schwinger, and Feynman, the formalism was raised from the status of ...

Polaritonics: from microcavities to sub-wavelength confinement
Nanophotonics, 2019 Following the initial success of cavity quantum electrodynamics in atomic systems, strong coupling between light and matter excitations is now achieved in several solid-state set-ups.

Angewandte Chemie, EarlyView.Precise building block design of poly(ionic liquids) creates an opportunity to achieve ionic conductivity, energy storage, and multi‐value logic in one material while eliminating elaborate fabrication processes. ABSTRACT In these studies, we developed a new generation of polymeric materials capable of electrical energy storage and forming higher‐than ...

Quantum Electrodynamics at Large Distances II: Nature of the Dominant Singularities
, 1995 Accurate calculations of macroscopic and mesoscopic properties in quantum electrodynamics require careful treatment of infrared divergences: standard treatments introduce spurious large-distances effects.
