Earth and Space Science, Volume 13, Issue 7, July 2026.Abstract We investigate the high‐latitude Joule heating in a recently developed high‐resolution configuration of the WACCM‐X whole‐atmosphere model coupled to the MAGE model. Model resolution and geomagnetic forcing effects during the severe (Kp>8) $(Kp > 8)$ geomagnetic storm on 24 August 2005 are analyzed, distinguishing storm peak and recovery ...

Advanced Classical Electrodynamics
, 2017 This textbook introduces advanced classical electrodynamics using modern mathematical techniques, with an emphasis on physical concepts. Connections to field theory and general relativity are highlighted while the book still serves as the basis for a one-

Insights on Lightning‐Induced Remanent Magnetization From High‐Current Impulse Experiments
Journal of Geophysical Research: Solid Earth, Volume 131, Issue 7, July 2026.Abstract Lightning strikes generate intense transient magnetic fields capable of inducing strong and complex remanent magnetizations in rocks, potentially overprinting their original paleomagnetic record. To investigate the mechanisms and outcomes of lightning‐induced remanent magnetization, we conducted controlled high‐current impulse experiments on ...

Classical electrodynamics in a space with spin noncommutativity of coordinates
Physics Letters B, 2016 We propose a relativistic Lorentz-invariant spin-noncommutative algebra. Using the Weyl ordering of noncommutative position operators, we find a mapping from a space of commutative functions into space of noncommutative functions.

Earth and Space Science, Volume 13, Issue 7, July 2026.Abstract Auroral transport models (ATMs) play an important role in quantitative studies of optical auroras, their driving mechanisms, and their effects on the ionosphere and thermosphere. TREx‐ATM was initially developed as the support model for the Transition Region Explorer (TREx) mission, and has gained increasing applications in the community in ...

Quantum-Classical Correspondence in Nonrelativistic Electrodynamics [PDF]
, 1999 A form of classical electrodynamic field exists which gives exact agreement with the operator field of quantum electrodynamics (QED) for the Lamb shift of a harmonically bound point electron. Here it is pointed out that this form of classical theory with

Physics Letters B, 2018 The expression for the total angular momentum carried by a laser optical vortex beam, splits, in the paraxial approximation, into two terms which seem to represent orbital and spin angular momentum respectively.

Space Weather, Volume 24, Issue 7, July 2026.Abstract This study investigates the co‐evolution of geomagnetic field disturbances with ionospheric parameters and their characteristic latitudinal signatures by conducting a location and time‐dependent analysis of the 07–12 October 2024 events, to fill crucial gaps in understanding the coupled response of the magnetosphere‐ionosphere system. This has

Space Weather, Volume 24, Issue 7, July 2026.Abstract Geomagnetically Induced Currents (GICs) are a key space weather hazard to ground‐based infrastructure, and can cause mis‐operation or even equipment failure. The solar wind interacts with the Earth's geomagnetic field, causing the magnetic field at ground level to vary with time.
