Qualitative investigation into students’ use of divergence and curl in electromagnetism

Physical Review Physics Education Research, 2016
Many students struggle with the use of mathematics in physics courses. Although typically well trained in rote mathematical calculation, they often lack the ability to apply their acquired skills to physical contexts.

Principal modes of Maxwell’s equations

, 2018
This chapter reviews the use of principal modes—states which are maximally correlated between two subspaces and hence form pairs unique up to phase factors—in solving Maxwell’s equations and analysing these solutions for nanoparticles and structures. The

Photonic‐Enabled Energy‐Efficient Transparent Neuromorphic Computing Devices: A Review

Advanced Science, EarlyView.
Transparent photonic neuromorphic computing devices merge optics and brain‐inspired computing to overcome von Neumann bottlenecks with ultrafast, low‐energy processing. By exploiting transparent oxides, 2D materials, phase‐change materials, and hybrid heterostructures, these platforms enable photonic synapses, memory, and logic for see‐through edge ...

Analytical solutions of 1D Maxwell’s equations via infinite-order expansions

Results in Applied Mathematics
Analytical solutions to Maxwell’s equations are essential for understanding the causal and instantaneous behavior of electromagnetic fields, yet they are challenging to obtain in open-space settings with general initial values and source terms. This work

Bidirectional Disulfide Metathesis Enables Recycling of High‐Performance Thermoset Networks

Advanced Science, EarlyView.
A cyclic aromatic disulfide comonomer enables dual‐mode recyclable pDCPD thermosets through bidirectional disulfide metathesis. The resulting networks combine enhanced mechanical performance with thermal reprocessability and chemical depolymerization into reusable oligomeric fragments, allowing regeneration of high‐performance thermosets with minimal ...

A Unifying Thermodynamic Model for Phase Separation and Aging of Biopolymers

Advanced Science, EarlyView.
Phase separation and aging of intrinsically disordered proteins are placed in a unifying framework. A thermodynamically consistent time‐dependent version of associating‐polymer theory shows how the processes are intricately coupled. Assuming aging to occur through interacting sites resulting from reversible conformational transitions, the model ...

The electromagnetic field’s quantum nature and spin

AIP Advances
The interaction of the electron (charge) with the electromagnetic field is investigated using the minimum coupling prescription, in which the electron’s spin appears in the Dirac and Pauli–Schrödinger equations.

Charged participants and their electromagnetic fields in an expanding fluid

Physics Letters B
We investigate the space-time dependence of electromagnetic fields produced by charged participants in an expanding fluid. To address this problem, we need to solve the Maxwell's equations coupled to the hydrodynamics conservation equation, specifically ...

Maxwell’s Equations and Occam’s Razor

, 2017
In this paper a straightforward application of Occam’s razor principle to Maxwell’s equation shows that only one entity, the electro-magnetic four-potential, is at the origin of a plurality of concepts and entities in physics.
