Non-Equilibrium Quantum Electrodynamics [PDF]

, 1997
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.

Non-Relativistic Quantum Electrodynamics and the Coulomb Interaction

Physics
This review explores the foundations of non-relativistic quantum electrodynamics (QED) and its application to atoms and molecules. It follows the traditional route of placing classical electrodynamics in an Hamiltonian framework, followed by Dirac’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.

Ion‐Lock Storage With Multi‐Logic Circuitry Gated by Polar–Dipolar Interactions in Poly(Ionic Liquids)

Angewandte Chemie, Volume 138, Issue 19, 4 May 2026.
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 ...

The relation between classical and quantum electrodynamics [PDF]

, 2008
In this article it is presented the idea that quantum electrodynamics presents intrinsic limitations in the description of physical processes that makes it impossible to recover from it the type of description we have with classical electrodynamics.
