Constraining Born-Infeld-like Nonlinear Electrodynamics Using Hydrogen's Ionization Energy

open access: yes, 2017
In this work, the hydrogen's ionization energy was used to constrain the free parameter $b$ of three Born-Infeld-like electrodynamics namely Born-Infeld itself, Logarithmic electrodynamics and Exponential electrodynamics.

Noise and Breakdown Characterization of SPAD Detectors with Time-Gated Photon-Counting Operation

open access: yesSensors, 2021
Being ready-to-detect over a certain portion of time makes the time-gated single-photon avalanche diode (SPAD) an attractive candidate for low-noise photon-counting applications. A careful SPAD noise and performance characterization, however, is critical

Mapping nonlinear gravity into General Relativity with nonlinear electrodynamics

open access: yes, 2018
We show that families of nonlinear gravity theories formulated in a metric-affine approach and coupled to a nonlinear theory of electrodynamics can be mapped into General Relativity (GR) coupled to another nonlinear theory of electrodynamics. This allows

Area and Bandwidth Enhancement of an n+/p-Well Dot Avalanche Photodiode in 0.35 μm CMOS Technology

open access: yesSensors, 2023
This paper presents a CMOS-integrated dot avalanche photodiode (dot-APD) that features a small central n+/p-well hemispherical cathode/p-well structure circularly surrounded by an anode ring.

Wave propagation in axion electrodynamics

open access: yes, 2007
In this paper, the axion contribution to the electromagnetic wave propagation is studied. First we show how the axion electrodynamics model can be embedded into a premetric formalism of Maxwell electrodynamics.

Massive Electrodynamics and the Magnetic Monopoles [PDF]

open access: yes, 1995
We investigate in detail the problem of constructing magnetic monopole solutions within the finite-range electrodynamics (i.e., electrodynamics with non-zero photon mass, which is the simplest extension of the standard theory; it is fully compatible with

Spontaneous Symmetry Breaking at Two Loop in 3-d Massless Scalar Electrodynamics [PDF]

open access: yes, 1996
In three dimensional Maxwell-Chern-Simons massless scalar electrodynamics with $ \phi^6$ coupling, the $U(1)$ symmetry is spontaneously broken at two loop order regardless of the presence or absence of the Maxwell term.

Prospects for statistical tests of strong-field quantum electrodynamics with high-intensity lasers

open access: yesHigh Power Laser Science and Engineering, 2023
Exploiting high-energy electron beams colliding into high-intensity laser pulses brings an opportunity to reach high values of the dimensionless rest-frame acceleration $\chi$ and thereby invoke processes described by strong-field quantum ...

The relation between classical and quantum electrodynamics [PDF]

open access: yes, 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.

Causal Structure and Birefringence in Nonlinear Electrodynamics

open access: yes, 2014
We investigate the causal structure of general nonlinear electrodynamics and determine which Lagrangians generate an effective metric conformal to Minkowski.
