Magnetostatic twists in room-temperature skyrmions explored by nitrogen-vacancy center spin texture reconstruction [PDF]
Nature Communications, 2018 The Dzyaloshinskii-Moriya interaction (DMI) is crucial to the stabilization of skyrmions but the contribution is not well understood. Here, the authors provide a methodology using the single electron spin of a nitrogen-vacancy center to image the fine ...

Coherent quantum control of nitrogen-vacancy center spins near 1000 kelvin [PDF]
Nature Communications, 2019 The spins of nitrogen vacancy centres have been shown to be sensitive, high-temperature quantum probes of magnetic fields but the usual readout scheme fails above 550 K. Here the authors demonstrate coherent control and sensing up to 1000 K by using fast

A superradiant maser with nitrogen-vacancy center spins [PDF]
Science China Physics, Mechanics & Astronomy, 2021 Recent experiments have demonstrated Rabi-oscillations, superradiant pulses and stimulated emission from negatively-charged nitrogen-vacancy ($\mathrm{NV}^{-}$) center spins in microwave resonators. These phenomena witness the kind of collective and strong coupling which has been prerequisite for observation of superradiant lasing in the optical ...

Decoherence Control of Nitrogen-Vacancy Centers [PDF]
Scientific Reports, 2017 AbstractQuantum mechanical systems lose coherence through interacting with external environments—a process known as decoherence. Although decoherence is detrimental for most of the tasks in quantum information processing, a substantial degree of decoherence is crucial for boosting the efficiency of quantum processes, for example, in quantum biology and

Conversion of neutral nitrogen-vacancy centers to negatively charged nitrogen-vacancy centers through selective oxidation [PDF]
Applied Physics Letters, 2010 The conversion of neutral nitrogen-vacancy centers to negatively charged nitrogen-vacancy centers is demonstrated for centers created by ion implantation and annealing in high-purity diamond. Conversion occurs with surface exposure to an oxygen atmosphere at 465 °C. The spectral properties of the charge-converted centers are investigated.
