Baryogenesis and CMB spectral distortion from Axions
Zhenhao Zhang, Mingqiu Li, Sichun Sun
We discuss a mechanism for generating the baryon asymmetry in the early universe. We show that an axion-like particle can modify the related gauge field configurations in the Stand…
Axion Dark Matter Modulated Spin Wave Interferometry
Jiayi Liu, Chen-Hui Xie, Runyu Lei +3
We propose a novel asymmetric spin wave interferometer to detect ultralight axion dark matter. The axion modulates spin-wave properties via a weak effective magnetic field in ferro…
Emerging axion detection in artificial magnetoelectric materials
Runyu Lei, Chen-Hui Xie, Jiayi Liu +5
Axions are considered a key component of dark matter, characterized by very weak couplings to fermions and Chern-Simons couplings to gauge fields. We propose a novel detection mech…
Detecting gravitational waves with spin systems
Jiamin Liang, Mingqiu Li, Yu Gao +3
The observation of gravitational waves has opened a new window into the Universe through gravitational-wave astronomy. However, high-frequency gravitational waves remain undetected…
