On-chip Radio Frequency Maser
Hongliang Wu, Zhengtao Wang, Yuchen Han +6
Room-temperature solid-state masers offer exceptional frequency selectivity and ultra-low noise for weak-signal detection. However, their reliance on bulky metallic resonators has…

Detecting Axion Dark Matter with an Organic Molecular Maser
Hongliang Wu, Yuchen Han, Zhengtao Wang +7
We present a novel quantum sensing approach to search for axion-electron interactions around the axion mass of 6 \mueV. In this region, laboratory searches are relatively scarce, a…
