Dark Photon Dark Matter Radio Signal from the Milky Way Electron Density
Ariel Arza
We consider Thomson-like processes between dark matter dark photons and free electrons in the Milky Way. The result is a radio signal background that can be detectable with current…
Listening for echo from the stimulated axion decay with the 21 CentiMeter Array
Ariel Arza, Quan Guo, Lei Wu +4
The axion is a hypothetical elementary particle that could solve the long-standing strong CP problem in particle physics and the dark matter mystery in the cosmos. Due to the stimu…
Electron corrections from axion dark matter
Ariel Arza, Jason Evans
We consider the effects of a local axion dark matter background on the of the electron. We calculate loop corrections to the photon-electron vertex and determine analytical f…
A Hunt for Magnetic Signatures of Hidden-Photon and Axion Dark Matter in the Wilderness
Ibrahim A. Sulai, Saarik Kalia, Ariel Arza +17
Earth can act as a transducer to convert ultralight bosonic dark matter (axions and hidden photons) into an oscillating magnetic field with a characteristic pattern across its surf…
Searching for axion streams with the echo method
Ariel Arza, Abaz Kryemadhi, Konstantin Zioutas
The axion dark matter echo technique, proposed in Ref. [1], aims to search for axion dark matter by detecting the electromagnetic echo coming from stimulated decay of ambient axion…
Vortex solutions in the presence of Dark Portals
Paola Arias, Ariel Arza, Fidel A. Schaposnik +2
The existence of hidden sectors weakly coupled to the visible one has been extensively studied as a way to extend the Standard Model (SM) and to provide a good dark matter candidat…
Earth as a transducer for axion dark-matter detection
Ariel Arza, Michael A. Fedderke, Peter W. Graham +2
We demonstrate that ultralight axion dark matter with a coupling to photons induces an oscillating global terrestrial magnetic field signal in the presence of the background geomag…
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…
Production of massive bosons from the decay of a massless particle beam
Ariel Arza
Taking a two interacting scalar toy model with interaction term , we study the production of particles coming from the decay of an asymptotic and highly occupied beam of…
Hidden Photon Dark Matter Interacting via Axion-like Particles
Paola Arias, Ariel Arza, Joerg Jaeckel +1
We investigate a scenario where the dark matter of the Universe is made from very light hidden photons transforming under a -symmetry. In contrast to the usual situation, ki…
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…
Duration of Classicality of an inhomogeneous quantum field with repulsive contact self-interactions
Ariel Arza, Sankha S. Chakrabarty, Seishi Enomoto +2
Quantum fields with large degeneracy are often approximated as classical fields. Here, we show how quantum and classical evolution of a highly degenerate quantum field with repulsi…
Production and detection of an axion dark matter echo
Ariel Arza, Pierre Sikivie
Electromagnetic radiation with angular frequency equal to half the axion mass stimulates the decay of cold dark matter axions and produces an echo, i.e. faint electromagnetic radia…
Photon enhancement in a homogeneous axion dark matter background
Ariel Arza
We study the propagation of photons in a homogeneous axion dark matter background. When the axion decay into two photons is stimulated, the photon field exhibits a parametric insta…
Parametric Resonance in Quantum Electrodynamics Vacuum Birefringence
Ariel Arza, Ricardo Gabriel Elias
Vacuum magnetic birefringence is one of the most interesting non-linear phenomena in quantum electrodynamics because it is a pure photon-photon result of the theory and it directly…
Birefringence and hidden photons
Ariel Arza, Jorge Gamboa
We study a model where photons interact with hidden photons and millicharged particles through a kinetic mixing term. Particularly, we focus in vacuum birefringence effects and we…
Effects of Weakly Interacting Slim Particles in Cavities with a Moving Boundary Condition
Ariel Arza
We study a Light Shinning Through the wall type setup with microwave cavities, where the regeneration cavity has a moving boundary condition oscillating harmonically. We find a par…
Photons and Dark Photons Through Breit-Wheeler Processes
Ariel Arza, Jorge Gamboa, Natalia Tapia
A variant of quantum electrodynamics coupled to a dark photon through a kinetic mixing is studied. The analogous of the light-light diagram becomes the conversion process $γ'γ' \to…
Mixing of photons with light pseudoscalars in time-dependent magnetic fields

The effects of an external time-dependent magnetic field in the conversion probability of photon-to-axion-like particles are studied. Our findings show that for a certain time regi…
Parametric Resonance and Dark Matter Axion-Like Particles
Ariel Arza, Paola Arias, Jorge Gamboa
We study the local effects of an external time-dependent magnetic field on axion-like particles assuming they are all the dark matter of the universe. We find that under suitable c…
Extracting Hidden-Photon Dark Matter From an LC-Circuit
Paola Arias, Ariel Arza, Babette Döbrich +2
We point out that a cold dark matter condensate made of gauge bosons from an extra hidden U(1) sector - dubbed hidden- photons - can create a small, oscillating electric density cu…
