High-quality Axion Strings from Monopole Strings
Nathaniel Craig, Amalia Madden
Five-dimensional 't Hooft-Polyakov monopole strings whose cores restore a non-abelian gauge symmetry become axion strings for extra-dimensional axions. The parametric separation be…
The FERMIACC: Agents for Particle Theory
Prateek Agrawal, Nathaniel Craig, Amalia Madden +1
We present the FERMIACC, a scaffolded reasoning model built on OpenAI agents designed to autonomously generate and quantitatively validate theory hypotheses for high energy physics…
Dark Matter Detection Using Phonon Sensing in Amorphous Materials
Itay M. Bloch, Simon Knapen, Xinran Li +2
We present a concept for a tabletop-scale detector with an amorphous target designed to search for dark matter absorption into phonon excitations. In crystalline materials, absorpt…
Broadband phonon production from axion absorption
Itay M. Bloch, Simon Knapen, Amalia Madden +1
We show that axion dark matter in the range meV 100 meV can incoherently excite phonons in crystal targets with unpolarised nuclear spins. This can occur thr…
