An unknown story: Majorana and the Pauli-Weisskopf scalar electrodynamics

, 2007
An account is given of an interesting but unknown theory by Majorana regarding scalar quantum electrodynamics, elaborated several years before the known Pauli-Weisskopf theory.

Foundations of Ghost Stability

Fortschritte der Physik, Volume 73, Issue 4, April 2025.
Abstract The authors present a new method to analytically prove global stability in ghost‐ridden dynamical systems. The proposal encompasses all prior results and consequentially extends them. In particular, it is shown that stability can follow from a conserved quantity that is unbounded from below, contrary to expectation.

Solving field equations in spinor electrodynamics [PDF]

arXiv, 2009
Solutions of classical and quantum equations of motion in spinor electrodynamics are constructed within the context of perturbation theory. The solutions possess a graphical representation in terms of diagrams.

Reproducing the Effects of Quantum Deformation in the Undeformed Jaynes‐Cummings Model

Advanced Quantum Technologies, EarlyView.
The inverse problem approach, where atomic probabilities are modulated according to a time‐dependent coupling, is studied for the Jaynes‐Cummings (JC) model. In particular, emphasis is placed on how to reproduce the effects of quantum deformation in a non‐deformed JC model.

Transverse recoil imprinted on free-electron radiation

Nature Communications
Phenomena of free-electron X-ray radiation are treated almost exclusively with classical electrodynamics, despite the intrinsic interaction being that of quantum electrodynamics. The lack of quantumness arises from the vast disparity between the electron

Quantum mechanics as electrodynamics of curvilinear waves [PDF]

arXiv, 2002
The suggested theory is the new quantum mechanics (QM) interpretation.The research proves that QM represents the electrodynamics of the curvilinear closed (non-linear) waves. It is entirely according to the modern interpretation and explains the particularities and the results of the quantum field theory.

Plasmonic Hot‐Carrier Engineering at Bimetallic Nanoparticle/Semiconductor Interfaces: A Computational Perspective

Small, Volume 21, Issue 11, March 19, 2025.
This perspective highlights the benefits of designing bimetallic particles (core‐shell or core‐satellite structures) with a plasmonic metal core and a less‐plasmonic metal shell, coupled with semiconductors, to address the challenge of plasmon‐induced hot‐carrier separation at monometallic particle‐semiconductor interfaces.

Asymptotic algebra of quantum electrodynamics [PDF]

Acta Phys.Polon. B36 (2005) 35-58, 2004
The Staruszkiewicz quantum model of the long-range structure in electrodynamics is reviewed in the form of a Weyl algebra. This is followed by a personal view on the asymptotic structure of quantum electrodynamics.

Topological phase transitions in the non-Abelian honeycomb lattice

, 2010
Ultracold Fermi gases trapped in honeycomb optical lattices provide an intriguing scenario, where relativistic quantum electrodynamics can be tested. Here, we generalize this system to non-Abelian quantum electrodynamics, where massless Dirac fermions ...

Woodward and Hoffmann on Secondary Orbital Interactions. How to Make a Fine Two‐Course Meal from Leftovers**

The Chemical Record, EarlyView.
In February through April 1965, Hoffmann devised several MO tools to explain the regiochemistry of the Diels‐Alder and the preference of the Cope reaction to proceed by the chair rather than boat orientations, when both were possible. The secret lay in secondary orbital interactions that were revealed through qualitative perturbation theory.
