Agent swarms: cooperation and coordination under stringent communications constraint

Paul Kinsler, Sean Holman, Andrew Elliott +2

Here we consider the communications tactics appropriate for a group of agents that need to "swarm" together in a highly adversarial environment. Specfically, whilst they need to co…

The surprising persistence of time-dependent quantum entanglement

Paul Kinsler, Martin W. McCall, Rupert F. Oulton +1

The mismatch between elegant theoretical models and the detailed experimental reality is particularly pronounced in quantum nonlinear interferometry (QNI). In stark contrast to the…

Temporal boundaries in electromagnetic materials

Jonathan Gratus, Rebecca Seviour, Paul Kinsler +1

Temporally modulated optical media are important in both abstract and applied applications, such as spacetime transformation optics, relativistic laser-plasma interactions, and dyn…

Temporary Singularities and Axions: an analytic solution that challenges charge conservation

Jonathan Gratus, Paul Kinsler, Martin W. McCall

We construct an analytic solution to Maxwell's equations that violates global charge conservation, by building on the possibilities demonstrated in [Foundations of Physics 49, 330…

Electromagnetism, Axions, and Topology: a first-order operator approach to constitutive responses provides greater freedom

Jonathan Gratus, Martin W. McCall, Paul Kinsler

We show how the standard constitutive assumptions for the macroscopic Maxwell equations can be relaxed. This is done by arguing that the Maxwellian excitation fields (D,H) should b…

An introduction to spatial dispersion: revisiting the basic concepts

Paul Kinsler

I describe three ways that the spatial properties of a wave propagation medium can cause dispersion, and propose that they should form the basics for correctly understanding and na…
