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…
Dark Matter Candidates and Searches
Nassim Bozorgnia, Joseph Bramante, James M. Cline +7
Astrophysical observations suggest that most of the matter in the cosmos consists of a new form that has not been observed on Earth. The nature and origin of this mysterious dark m…
Pi in the Sky: Neutron Stars with Exceptionally Light QCD Axions
Mia Kumamoto, Junwu Huang, Christian Drischler +2
We present a comprehensive study of axion condensed neutron stars that arise in models of an exceptionally light axion that couples to quantum chromodynamics (QCD). These axions so…
Experimental targets for dark photon dark matter
David Cyncynates, Zachary J. Weiner
Ultralight dark photon dark matter features distinctive cosmological and astrophysical signatures and is also supported by a burgeoning direct-detection program searching for its k…
Dimming Starlight with Dark Compact Objects
Joseph Bramante, Melissa D. Diamond, J. Leo Kim
We demonstrate a new technique to search for dark compact objects. When dark matter comprising a dark compact object interacts with photons, the compact object can disperse light t…
Resonant or asymmetric: The status of sub-GeV dark matter
Sowmiya Balan, Csaba Balázs, Torsten Bringmann +9
Sub-GeV dark matter (DM) particles produced via thermal freeze-out evade many of the strong constraints on heavier DM candidates but at the same time face a multitude of new constr…
