Aplikasi Aljabar Geometris Pada Teori Elektrodinamika Klasik

Jurnal Fourier, 2012
In this paper geometric algebra and its aplication in the theory of classical electrodynamic will  be studied. Geometric algebra provide many simplification and new insight in the theoretical formulation and physical aplication of theory.

Scalar QED as a toy model for higher-order effects in classical gravitational scattering

Journal of High Energy Physics, 2022
Quantum Electrodynamics (QED) serves as a useful toy model for classical observables in gravitational two-body systems with reduced complexity due to the linearity of QED.

Ionospheric Scintillation Induced by Hot Flow Anomalies via Particle Precipitation

AGU Advances, Volume 7, Issue 7, October 2026.
Abstract Ionospheric scintillation disrupts trans‐ionospheric radio signals and represents significant challenges for critical communication and navigation systems. Here we document that hot flow anomalies (HFAs), transient disturbances formed near Earth's bow shock, can contribute to scintillation near the cusp.

A Time‐Continuous Model of the 3D Ionospheric Current System and Associated Magnetic Fields in the Diurnal Variation Band

Journal of Geophysical Research: Space Physics, Volume 131, Issue 10, October 2026.
Abstract Ionospheric currents and their associated magnetic perturbations are difficult to predict due to the high variability of their driving mechanisms. In addition, the 3D structure of the currents is challenging to unravel due to the lack of direct observations within the current flow region, particularly in the E $E$‐layer.

A proposed measurement of optical orbital and spin angular momentum and its implications for photon angular momentum

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.

Nighttime Westward Equatorial Electrojet Observed During the January 2026 Geomagnetic Storm

Journal of Geophysical Research: Space Physics, Volume 131, Issue 10, October 2026.
Abstract The equatorial electrojet (EEJ) is a narrow band of zonal electric current flowing in the E‐region ionosphere within approximately ±2° $\pm 2{}^{\circ}$ latitude of the magnetic equator. At night, the EEJ is generally considered very weak because of low ionospheric conductivity.

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.

Thermospheric Neutral Species Reduced Order Probabilistic Emulator: Dimensionality Reduction

Space Weather, Volume 24, Issue 10, October 2026.
Abstract One area of significant interest for space operations is the application of physics‐based thermosphere models for accurate drag modeling. However, their computational complexity limits their use in operational settings. To address this, recently developed reduced‐order probabilistic emulators (ROPE) based on the Thermosphere‐Ionosphere ...

Large Rabi Splitting Driven by Plasmon‐Enhanced Hybrid Anapole States in Si–Au–WSe2 Heterostructures

Nanophotonics, Volume 15, Issue 18, 25 September 2026.
A silicon hybrid‐anapole microcavity coupled with a plasmonic array enables tripartite strong coupling with WSe2 excitons. Spatially extended field enhancement and coherent cavity–plasmon hybridization strengthen light–matter interactions, producing a giant 330 meV Rabi splitting at room temperature and offering a compact platform for low‐exciton ...
