Particle physics today faces the challenge of explaining the mystery of dark matter, the origin
of matter over anti-matter in the Universe, the origin of the neutrino masses, the apparent …

We give a detailed treatment of electromagnetic signals generated by gravitational waves
(GWs) in resonant cavity experiments. Our investigation corrects and builds upon previous …

The quantum chromodynamics (QCD) axion may modify the cooling rates of neutron stars
(NSs). The axions are produced within the NS cores from nucleon bremsstrahlung and …

We summarize the recent progress of the Axion Longitudinal Plasma Haloscope (ALPHA)
Consortium, a new experimental collaboration to build a plasma haloscope to search for …

The main mechanism responsible for Axion-Like-Particle (ALP) production in the early
universe is the so-called misalignment mechanism. Three regimes have been investigated …

In the scenario in which QCD axion dark matter is produced after inflation, the Universe is
populated by large inhomogeneities on very small scales. Eventually, these fluctuations will …

We investigate the effects of short axion kination eras on the energy spectrum of the
primordial gravitational waves corresponding to modes that reenter the Hubble horizon at …

The field of propagating quantum microwaves is a relatively new area of research that is
receiving increased attention due to its promising technological applications, both in …

We report the first experimental results obtained with the new haloscope of the QUAX
experiment located at Laboratori Nazionali di Frascati of INFN (LNF). The haloscope is …

We report on the extension of the spectral sensitivity of superconducting nanowire single-
photon detectors to a wavelength of 29 µm. To our knowledge, this represents the first …
