Dense pentacene cocrystal demonstrates room-temperature coherent control
Noella D'Souza, Guangzhao Chen, Madhur Parashar +13
Maximizing the number of addressable spins within a fixed volume can improve ensemble quantum sensor sensitivity, but dense packing usually increases dipolar interactions and excit…
`Maser-in-a-Shoebox': a portable plug-and-play maser device at room-temperature and zero magnetic-field
Wern Ng, Yongqiang Wen, Max Attwood +4
Masers, the microwave analogues of lasers, have seen a renaissance owing to the discovery of gain media that mase at room-temperature and zero-applied magnetic field. However, desp…
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…
Quasi-Continuous Cooling of a Microwave Mode on a Benchtop using Hyperpolarized NV Diamond
Wern Ng, Hao Wu, Mark Oxborrow
We demonstrate the cooling of a microwave mode at 2872 MHz through its interaction with optically spin-polarized NV centers in diamond at zero applied magnetic field, removing…
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…
Room-temperature quasi-continuous-wave pentacene maser pumped by an invasive Ce:YAG luminescent concentrator
Hao Wu, Xiangyu Xie, Wern Ng +4
We present in this work a quasi-continuous-wave (CW) pentacene maser operating at 1.45 GHz in the Earth's magnetic field at room temperature with a duration of 4 ms and an ou…
