Gravitational waves (GWs) generate oscillating electromagnetic effects in the vicinity of
external electric and magnetic fields. We discuss this phenomenon with a particular focus on …

The QCD axion has been postulated to exist because it solves the strong-CP problem.
Furthermore, if it exists axions should be created in the early Universe and could account for …

We show that, contrary to assertions in the literature, the main contribution to the axion-
photon coupling need not be quantized in the units proportional to $ e^ 2$. In particular, we …

The Maxwell equations and the constitutive relations describe the classical propagation of
electromagnetic waves in continuous matter. Here, we investigate the effects stemming from …

The QCD (Quantum ChromoDynamics) axion emerged as one of the best-motivated dark
matter candidates. In 2018, the Axion Dark Matter eXperiment (ADMX), one of the US …

In this work we study how CPT-odd Maxwell-Carroll-Field-Jackiw (MCFJ) electrodynamics
as well as a dimension-5 extension of it affect the optical activity of continuous media. The …

The most sensitive haloscopes that search for axion dark matter through the two photon
electromagnetic anomaly convert axions into photons through the mixing of axions with a …

A bstract The QCD axion or axion-like particles are candidates of dark matter of the universe.
On the other hand, axion-like excitations exist in certain condensed matter systems, which …

We examine a dielectric medium supporting a magnetic current in connection with optical
properties and energy propagation. The dispersion relations, propagating modes, and some …

First experimental results from a room-temperature tabletop phase-sensitive axion
haloscope experiment are presented. The technique exploits the axion-photon coupling …
