Reverse Circular Bragg Phenomenon

Martin W. McCall, Stefanos Fr. Koufidis

The axial propagation of circularly polarized light in an optically active structurally chiral medium is exactly solved via full electromagnetic analysis. Some symmetries of the sy…

Broadband Bragg phenomenon in a uniform medium

Martin W. McCall, Stefanos Fr. Koufidis

A new mechanism of Bragg reflection is identified, one that, remarkably, occurs in a uniform medium and relies on resonant tuning of the medium's parameters. Due to uniformity, ref…

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…

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…

Evaporating black-holes, wormholes, and vacuum polarisation: must they always conserve charge?

Jonathan Gratus, Paul Kinsler, Martin W. McCall

A careful examination of the fundamentals of electromagnetic theory shows that due to the underlying mathematical assumptions required for Stokes' Theorem, global charge conservati…
