Detecting the QCD axion via the ferroaxionic force with piezoelectric materials
Asimina Arvanitaki, Jonathan Engel, Andrew A. Geraci +3
We show that piezoelectric materials can be used to source virtual QCD axions, generating a new axion-mediated force. Spontaneous parity violation within the piezoelectric crystal…

Dyon Loops and Abelian Instantons
Isabel Garcia Garcia, Marius Kongsore, Ken Van Tilburg
We construct Abelian gauge field configurations that carry non-zero instanton number. Each such "Abelian instanton" is generated by a closed magnetic worldline in four-dimensional…

Orbital Dynamics of the Solar Basin
Cara Giovanetti, Robert Lasenby, Ken Van Tilburg
We study the dynamics of the solar basin -- the accumulated population of weakly-interacting particles on bound orbits in the Solar System. We focus on particles starting off on Su…
