Magnetoelectric Phase Transition and Axion Dynamics
Chen-Hui Xie, Runyu Lei, Jiayi Liu +4
Magnetoelectric phase transitions have been experimentally studied, but no macroscopic theory has been proposed to explain their dynamical origin. In this work, we assume that the…

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…
