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…
Gravitational waves from axion wave production
Mingqiu Li, Sichun Sun, Qi-Shu Yan +1
We consider a scenario with axions/axion-like particles Chern-Simons gravity coupling, such that gravitational waves can be produced directly from axion wave parametric resonance i…
