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 …

A bstract Standard axion electrodynamics has two closely related features. First, the
coupling of a massless axion field to photons is quantized, in units proportional to the …

A bstract The Witten effect implies the electromagnetic interactions between axions and
magnetic monopoles, and the quantum electromagnetodynamics (QEMD) properly …

We present new results of a room temperature resonant AC haloscope, which searches for
axions via photon upconversion. Traditional haloscopes require a strong applied DC …

It is known that haloscopes that search for dark matter axions via the axion-photon anomaly
are also sensitive to gravitational radiation through the inverse Gertsenshtein effect …

Recently, interactions between putative axions and magnetic monopoles have been
revisited by two of the authors. 1 It is shown that significant modifications to conventional …

We show that the QCD axion couples to the electromagnetic kinetic term at one loop. The
result is that if axions make up dark matter, they induce temporal variation of the fine …

Long-standing efforts to detect axions are driven by two compelling prospects, naturally
accounting for the absence of charge-conjugation and parity symmetry breaking in quantum …
