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 ...

Quantum Electrodynamics vacuum polarization solver
New Journal of Physics, 2021 The self-consistent modeling of vacuum polarization due to virtual electron-positron fluctuations is of relevance for many near term experiments associated with high intensity radiation sources and represents a milestone in describing scenarios of ...

$\pi^+\pi^+$ and $\pi^+\pi^-$ colliding in noncommutative space
, 2012 By studying the scattering process of scalar particle pion on the noncommutative scalar quantum electrodynamics, the non-commutative amendment of differential scattering cross-section is found, which is dependent of polar-angle and the results are ...

Quantum‐Classical Simulation of Quantum Field Theory by Quantum Circuit Learning
Annalen der Physik, EarlyView.Quantum circuit learning is employed to simulate quantum field theories (QFTs). By integrating a minimal qubit configuration and low‐depth circuits, the approach predicts real‐time dynamics accurately. It effectively simulates complex phenomena such as quench and chiral dynamics in a model of quantum electrodynamics, aligning well with classical ...

On Quantum Corrections to Chern-Simons Spinor Electrodynamics [PDF]
, 1997 We make a detailed investigation on the quantum corrections to Chern-Simons spinor electrodynamics. Starting from Chern-Simons spinor quantum electrodynamics with the Maxwell term $-1/(4\gamma){\int}d^3x F_{\mu\nu}F^{\mu\nu}$ and by calculating the ...

The stability of matter and quantum electrodynamics [PDF]
Current Developments in Mathematics, 2003 A survey of the stability of matter problem is given, starting with the stability of the hydrogen atom. The stablity of bulk matter with Coulomb potentials, with or without relativistic mechanics, and with or without magnetic fields is discussed. The final section discusses the stability of matter in a relativistic model with the Dirac operator as ...

Leaflet‐specific Structure and Dynamics of Solid and Polymer Supported Lipid Bilayers
Angewandte Chemie International Edition, Accepted Article.Polymer‐supported or tethered lipid bilayers serve as versatile platforms for mimicking plasma membrane structure and dynamics, yet the impact of polymer supports on lipid bilayers remains largely unresolved. In this study, we introduce a novel methodology that combines graphene‐induced energy transfer (GIET) with line‐scan fluorescence lifetime ...

A Physically-Motivated Quantisation of the Electromagnetic Field on Curved Spacetimes
Entropy, 2019 Recently, Bennett et al. (Eur. J. Phys. 37:014001, 2016) presented a physically-motivated and explicitly gauge-independent scheme for the quantisation of the electromagnetic field in flat Minkowski space.

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 $

Quantum electrodynamics in finite volume and nonrelativistic effective field theories
Physics Letters B, 2016 Electromagnetic effects are increasingly being accounted for in lattice quantum chromodynamics computations. Because of their long-range nature, they lead to large finite-size effects over which it is important to gain analytical control. Nonrelativistic
