Probing Axion via Mössbauer Spectroscopy
Shengyi Liu, Kun-Feng Lyu, Jie Meng +3
We propose using the ultra-narrow 88 keV Mössbauer transition in Ag to search for QCD axion dark matter. The sub-eV axion field oscillates coherently, inducing a time-vary…

QCD Axion Domain Walls from Super-Cooling First Order Phase Transition
Kun-Feng Lyu, Yue Zhao
The QCD axion is a well-motivated hypothetical particle beyond the Standard Model (SM) and a compelling dark matter candidate. Its relic abundance is highly sensitive to the therma…
