Quantum measurement systems and applications to particle physics and cosmology
Masashi Hazumi
There are new detector proposals and R&D that utilize quantum enhancements not previously adopted. Examples include superconducting quantum sensors, atom interferometry, and quantu…
Nuclear Spin Metrology with Nitrogen Vacancy Center in Diamond for Axion Dark Matter Detection
So Chigusa, Masashi Hazumi, Ernst David Herbschleb +3
We present a method to directly detect the axion dark matter using nitrogen vacancy centers in diamonds. In particular, we use metrology leveraging the nuclear spin of nitrogen to…
Light Dark Matter Search with Nitrogen-Vacancy Centers in Diamonds
So Chigusa, Masashi Hazumi, Ernst David Herbschleb +2
We propose new ideas to directly search for light dark matter, such as the axion or the dark photon, by using magnetometry with nitrogen-vacancy centers in diamonds. If the dark ma…
The Simons Observatory: Design, Integration, and Current Status of Small Aperture Telescopes
Aashrita Mangu, Lance Corbett, Sanah Bhimani +14
The Simons Observatory (SO) is a cosmic microwave background (CMB) survey experiment located in the Atacama Desert in Chile at an elevation of 5200 meters, nominally consisting of…
Zero Casimir Force in Axion Electrodynamics and the Search for a New Force
Yohei Ema, Masashi Hazumi, Hideo Iizuka +2
We point out that there is a stable configuration of metal plates where the Casimir force is vanishing in axion electrodynamics. We consider a concrete setup involving Weyl semimet…
