Time as a Quantum Observable, Canonically Conjugated to Energy, and Foundations of Self-Consistent Time Analysis of Quantum Processes

Advances in Mathematical Physics, 2009
Recent developments are reviewed and some new results are presented in the study of time in quantum mechanics and quantum electrodynamics as an observable, canonically conjugate to energy. This paper deals with the maximal Hermitian (but nonself-adjoint)

On the Emergence of the Coulomb Forces in Quantum Electrodynamics

Advances in High Energy Physics, 2017
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.

Stochastic Electrodynamics: The Closest Classical Approximation to Quantum Theory

Atoms, 2019
Stochastic electrodynamics is the classical electrodynamic theory of interacting point charges which includes random classical radiation with a Lorentz-invariant spectrum whose scale is set by Planck’s constant.

Large N external-field quantum electrodynamics

Journal of High Energy Physics, 2022
We advocate the study of external-field quantum electrodynamics with N charged particle flavors. Our main focus is on the Heisenberg-Euler effective action for this theory in the large N limit which receives contributions from all loop orders.

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 ...

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 ...

Quantum electrodynamical formulation of photochemical acid generation and its implications on optical lithography

ETRI Journal
The photochemical acid generation is refined from the first principles of quan-tum electrodynamics. First, we briefly review the formulation of the quantum theory of light based on the quantum electrodynamics framework to establish the probability of ...

Radiative nonrecoil nuclear finite size corrections of order α(Zα)5 to the Lamb shift in light muonic atoms

Physics Letters B, 2017
On the basis of quasipotential method in quantum electrodynamics we calculate nuclear finite size radiative corrections of order α(Zα)5 to the Lamb shift in muonic hydrogen and helium.

Resurgence in the scalar quantum electrodynamics Euler–Heisenberg Lagrangian

European Physical Journal C: Particles and Fields
We explore the ideas of resurgence and Padé–Borel resummation in the Euler–Heisenberg Lagrangian of scalar quantum electrodynamics, which has remained largely unexamined in these contexts.

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.
