Coherent versus incoherent amplification: from parametric resonance to the kinetic regime in stimulated axion decay
Clemente Smarra, Elisa Todarello
Although the spontaneous decay of axions into two photons is extremely slow on cosmological timescales, it can be strongly enhanced in environments with large bosonic occupation nu…
GUEST: Gravitational Universe Exploration with Satellite Tracking. A passive satellite laser-ranging mission for the dark gravitational Universe
Diego Blas, Aurélien Hees, F. Javier Atapuerca +78
GUEST is a space mission concept whose central objective is the detection of gravitational waves (GWs) in the microhertz band -- a physics-rich frequency window that no other prese…
Using the Pericentre Precession of LAGEOS II to Constrain Quadratically Coupled Ultralight Dark Matter
Clare Burrage, Angus Macdonald, Elisa Todarello
It has been proposed that feebly interacting ultralight scalars may constitute the dark matter content of the universe. Models describing the interactions of a dark matter scalar w…
Axions at the meV Crossroads: Theory, Cosmology, Astrophysics, and Experiments
Michele Cicoli, Francesco D'Eramo, Luca Di Luzio +18
The meV mass range has emerged as a focal point in axion physics, where advances in theory, cosmology, astrophysics, and experimental techniques converge. Axions in this mass range…
Impact of cavities on the detection of quadratically coupled ultra-light dark matter
Clare Burrage, Angus Macdonald, Michael P. Ross +2
Ultra-light scalar fields may explain the nature of the dark matter in our universe. If such scalars couple quadratically to particles of the Standard Model the scalar acquires an…
Comment on "Axion Electrodynamics in the Presence of Current Sources"
Thomas Schwetz, Elisa Todarello
In this note we refute the critique raised in a preprint by J.~Berger and A.~Bhoonah~\cite{Berger:2023muj} on the method used in our earlier paper, Beutter et al.~\cite{Beutter:201…
A self-consistent wave description of axion miniclusters and their survival in the galaxy
Virgile Dandoy, Thomas Schwetz, Elisa Todarello
We present a solution of the Schrödinger-Poisson system based on the WKB ansatz for the wave function. In this way we obtain a description of a gravitationally bound clump of axion…
The axion dark matter echo: a detailed analysis
Ariel Arza, Elisa Todarello
It was recently shown that a powerful beam of radio/microwave radiation sent out to space can produce detectable back-scattering via the stimulated decay of ambient axion dark matt…
How to suppress exponential growth -- on the parametric resonance of photons in an axion background
Ariel Arza, Thomas Schwetz, Elisa Todarello
Axion--photon interactions can lead to an enhancement of the electromagnetic field by parametric resonance in the presence of a cold axion background, for modes with a frequency cl…
Axion-electrodynamics: a quantum field calculation
Marc Beutter, Andreas Pargner, Thomas Schwetz +1
An axion background field induces tiny oscillating electric and magnetic fields in an external static magnetic field. This signature is used to search for axion dark matter. We use…
