Axions beyond gen 2

C Boutan, G Carosi, LJ Rosenberg… - … Journal of Modern …, 2023 - World Scientific
The QCD (Quantum ChromoDynamics) axion emerged as one of the best-motivated dark
matter candidates. In 2018, the Axion Dark Matter eXperiment (ADMX), one of the US …

Orbital-flop transition of superfluid 3He in anisotropic silica aerogel

MD Nguyen, J Simon, JW Scott, AM Zimmerman… - Nature …, 2024 - nature.com
Superfluid 3He is a paradigm for odd-parity Cooper pairing, ranging from neutron stars to
uranium-based superconducting compounds. Recently it has been shown that 3He, imbibed …

Magnetic Susceptibility of Andreev Bound States in Superfluid

JW Scott, MD Nguyen, D Park, WP Halperin - Physical review letters, 2023 - APS
Nuclear magnetic resonance measurements of the magnetic susceptibility of superfluid He 3
imbibed in anisotropic aerogel reveal anomalous behavior at low temperatures. Although …

Effect of Magnetic Impurities on Superfluid

AM Zimmerman, MD Nguyen, JW Scott, WP Halperin - Physical review letters, 2020 - APS
It is known that both magnetic and nonmagnetic impurities suppress unconventional
superconductivity. Here we compare their effect on the paradigm unconventional …

Planar and Nematic Aerogels: DLCA and Superfluid 3He

MD Nguyen, JS Simon, JW Scott, YC Tsai… - arXiv preprint arXiv …, 2023 - arxiv.org
We perform cluster aggregation simulations to model the structure of anisotropic aerogel. By
biasing the diffusion process, we are able to obtain two distinct types of globally anisotropic …

Macroscopic Quantum states at Ultra-low Temperature

W Halperin - events.fnal.gov
New anisotropic states of superfluid 3He have been studied at ultra-low temperatures. They
are similar to those in the superconducting compound UPt3. I will discuss and compare …
