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…
Visualizing modified spin-wave wavefronts near magnetic defects and domains using nitrogen-vacancy centers
Wenxin Cheng, Chang Liu, Dekun Shen +12
Direct, real-space imaging of spin-wave propagation and wavefronts in magnetic materials is crucial for advancing both fundamental understanding of spin dynamics and the developmen…
Fractional phase slips across the charge-density-wave domain walls in 1-T TiSe2
Haotian Zhang, Zihao Song, Zhongchen Xu +9
The microscopic origin of the charge density wave (CDW) in 1\textit{T}-TiSe remains controversial, with competing scenarios based on phonon-driven lattice instability and elect…
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…
