Statistical Properties of Dayside Single‐Crest Structure of the Equatorial Ionization Anomaly Derived From Global Ionospheric Maps

Space Weather, Volume 24, Issue 7, July 2026.
Abstract The classical Equatorial Ionization Anomaly (EIA) is characterized by two separated plasma accumulation regions off the geomagnetic equator and a plasma depletion region in between. Deviations from the typical double‐crest structure, including the single crest and multiple crests, have been observed.

Mercury's Alfvén Wing Current System Under Sub‐Alfvénic Solar Wind Conditions: Insights From Global MHD Simulations

Geophysical Research Letters, Volume 53, Issue 12, 28 June 2026.
Abstract Mercury's proximity to the Sun results in the lowest average Alfvénic Mach number in the upstream solar wind compared to any other planet. Under extreme conditions, the upstream Alfvén speed can exceed the solar wind speed, resulting in a sub‐Alfvénic interaction in which standing Alfvén wings form.

Exploring light propagation in nonlinear electrodynamics: phase and group velocities and related phenomena

European Physical Journal C: Particles and Fields
Nonlinear electrodynamics has been an important area of research for a long time. Investigations based on nonlinear Lagrangians, such as Euler–Heisenberg and Born–Infeld, are instrumental in exploring the limits of classical and quantum field theories ...

Derivation of the cut-off length from the quantum quadratic enhancement of a mass in vacuum energy constant Lambda

European Physical Journal C: Particles and Fields, 2018
Ultraviolet self-interaction energies in field theory sometimes contain meaningful physical quantities. The self-energies in such as classical electrodynamics are usually subtracted from the rest mass.

Hot Electron‐Informed Quantum Plasmonics in Nanoparticle‐on‐Mirror Nanocavities

Nanophotonics, Volume 15, Issue 12, 25 June 2026.
A computational model for ultrafast optical modulation of quantum phenomena at plasmonic metal interfaces is developed. Focusing on nanoparticle‐on‐mirror nanocavities, it describes temperature‐induced variations in electronic quantum behavior. This facilitates analysis of quantum plasmonics in non‐equilibrium systems, thereby expanding the realm of ...

A reformulation of mechanics and electrodynamics

Heliyon, 2017
Classical mechanics, as commonly taught in engineering and science, are confined to the conventional Newtonian theory. But classical mechanics has not really changed in substance since Newton formulation, describing simultaneous rotation and translation ...

Stability and thermodynamic topology of logarithmic nonlinear electrodynamics black holes with exponential entropy corrections

Physics Letters B
We investigate the thermodynamic stability and phase structure of black holes in logarithmic nonlinear electrodynamics (LNED) with non-perturbative exponential corrections to the Bekenstein–Hawking entropy.
