Heterodyne-Enhanced Sensing of Cavity Mode Spacing
Aaron D. Spector, Laura Roberts
Characterizing the frequencies of resonant modes is critical to a wide variety of experimental applications. In this work we demonstrate a heterodyne-enhanced sensing scheme capabl…

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…

Demonstration of an interferometric technique for measuring vacuum magnetic birefringence with an optical cavity
Aaron D. Spector, Todd Kozlowski, Laura Roberts
Vacuum magnetic birefringence (VMB) is an effect predicted by quantum electrodynamics, in which the vacuum behaves as a non-linear optical medium and exhibit a birefringence in the…
