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…

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…
