Student perspectives in quantum physics [PDF]

, 2008
Introductory courses in classical physics are promoting in students a realist perspective, made up in part by the belief that all physical properties of a system can be simultaneously specified, and thus determined at all future times. Such a perspective

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.

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.

Quantifying the Effects of Parameters in Widespread Solar Energetic Particle Events with EPREM

The Astrophysical Journal
The Energetic Particle Radiation Environment Model (EPREM) solves the focused transport equation on a Lagrangian grid in a frame comoving with the solar wind plasma and simulates the acceleration and transport of solar energetic particles (SEPs) in the ...

A Global Lithospheric Magnetic Field Model Derived From Multi‐Satellite Gradient Observations and Regional Aeromagnetic Data

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 10, October 2026.
Abstract Using gradient data from the Macau Science Satellite‐1 (MSS‐1), CHAMP, Swarm‐A, and Swarm‐C satellites, together with aeromagnetic model data from China, we built the China‐specific Global Gradient Lithospheric Magnetic Model (CGGLM). The new model reaches spherical harmonic degree 140 and uses the Iteratively Re‐weighted Least‐Squares method ...

The Effects of ICME Composition on the Sputtered Component of the Lunar Exosphere

Journal of Geophysical Research: Planets, Volume 131, Issue 10, October 2026.
Abstract Charged‐particle sputtering is a fundamental process that contributes to the generation of the Moon’s neutral exosphere. Neutral sputtering rates are dependent on the speed, flux, and composition of the incident charged‐particle populations, all of which are variable at the Moon’s orbit.

Active Dust Devils in the Rosalind Franklin Rover Landing Site in Oxia Planum, Mars

Journal of Geophysical Research: Planets, Volume 131, Issue 10, October 2026.
Abstract The Rosalind Franklin rover will land in Oxia Planum, Mars, in the second half of 2030. The mission relies on solar arrays to provide electrical power to the rover, so knowledge about dust‐clearing rates is important for science operations.

Variation of Global Ionospheric Scintillation and Its Effect on GPS Kinematic PPP‐AR Performance During Geomagnetic Storms in Solar Cycle 25: A Statistical Analysis

Space Weather, Volume 24, Issue 10, October 2026.
Abstract Enhanced small‐scale ionospheric irregularities during geomagnetic storms can disturb Global Navigation Satellite System (GNSS) carrier‐phase tracking and are associated with reduced stability of ambiguity‐fixed precise point positioning (PPP‐AR), but their impact on kinematic positioning remains insufficiently quantified.

Updating the Electrostatic Model for Dust Impact Detection with Antenna Instruments

The Astrophysical Journal
Antenna instruments deployed in space are known to be sensitive to dust impacts, and the detected signals can be used to characterize the dust populations within the solar system.
