Move aside pentacene: Diazapentacene doped para-terphenyl as a zero-field room-temperature maser with strong coupling for cavity quantum electrodynamics
Wern Ng, Xiaotian Xu, Max Attwood +4
Masers, the microwave analogue of lasers, promise to deliver ultra-low noise amplification of microwave signals for use in medical MRI imaging and deep-space communication. Researc…

Bench-top Cooling of a Microwave Mode using an Optically Pumped Spin Refrigerator
Hao Wu, Shamil Mirkhanov, Wern Ng +1
We experimentally demonstrate the temporary removal of thermal photons from a microwave mode at 1.45 GHz through its interaction with the spin-polarized triplet states of photo-exc…
