Dyonic lattices, -angles and axions in the Standard Model
Rodrigo Alonso, Francesca Chadha-Day, Despoina Dimakou +2
We investigate the implications of the Witten effect in the Standard Model with a general global gauge group structure and determine the values of the three -parameters that lea…
Discovering the Axiverse via Fifth Forces
Martin Bauer, Francesca Chadha-Day, Alexander Eberhart
If the Universe is described by string theory or other extensions of the Standard Model, several light, axion-like states are predicted to exist. However, most experiments only sea…
WISPedia -- the WISPs Encyclopedia
Conrado Albertus, Francesca Chadha-Day, Arturo de Giorgi +8
The Weakly-Interacting Slim Particle encyclopedia (WISPedia) is a comprehensive reference work dedicated to the systematic compilation of theoretical models, Effective Field Theori…
The COSMIC WISPers White Paper: The physics case for Weakly Interacting Slim Particles
Ariel Arza, Deniz Aybas, Shyam Balaji +124
Axions and other very weakly interacting slim particles (WISPs), with masses below 1 GeV, arise naturally in many extensions of the Standard Model of particle physics. In particula…
Searching for axions with time resolved pulsar polarimetry
Francesca Chadha-Day, Tanmay Kumar Poddar
Pulsars possess strong dipole magnetic fields that can source axion fields through the axion-photon interaction. Pulsars may therefore be surrounded by axion field configurations o…
Axion superradiance
Francesca Chadha-Day
Light bosonic fields may suffer an instability around a rotating compact object. This process, known as superradiance, leads to the exponential amplification of the field around a…
ALP Anarchy
Francesca Chadha-Day, James Maxwell, Jessica Turner
String theory models generically predict the existence of multiple axion-like particle (ALP) fields, yet the majority of both theoretical and experimental works have assumed only o…
Superradiance in Stars: Non-equilibrium approach to damping of fields in stellar media
Francesca Chadha-Day, Björn Garbrecht, Jamie McDonald
Superradiance in black holes is well-understood but a general treatment for superradiance in stars has until now been lacking. This is surprising given the ease with which we can o…
Axion-like particle oscillations
Francesca Chadha-Day
String theory compactifications may generate many light axion-like particles (ALPs) with weak couplings to electromagnetism. In general, a large number of ALPs may exist, with a li…
Axion Dark Matter: What is it and Why Now?
Francesca Chadha-Day, John Ellis, David J. E. Marsh
The axion has emerged in recent years as a leading particle candidate to provide the mysterious dark matter in the cosmos, as we review here for a general scientific audience. We d…
Axion Quasiparticles for Axion Dark Matter Detection
Jan Schütte-Engel, David J. E. Marsh, Alexander J. Millar +7
It has been suggested that certain antiferromagnetic topological insulators contain axion quasiparticles (AQs), and that such materials could be used to detect axion dark matter (D…
