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…
Entangled Telecom Photon Generation using Twisted Van der Waals Crystals
Nidhin Prasannan, Konstantinos Mourzidis, Vishwas Jindal +11
Nanoscale quantum light sources are essential building blocks for integrated quantum photonic systems. Here, we report a wavelength-scale entangled-photon source based on van der W…
Atomic-scale visualization of d-wave altermagnetism
Daran Fu, Liu Yang, Yi Shen +7
Altermagnetism is a newly identified magnetic phase, distinct from conventional ferromagnetism and antiferromagnetism. It exhibits no net magnetization while breaking time-reversal…
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…
