Laser writing of preferentially orientated nitrogen-vacancy centers in diamond [PDF]

Carbon Trends, 2023
Nitrogen-vacancy centers in diamond have gained widespread attention as quantum systems that can be applied in quantum information devices. The excellent properties of quantum devices can be enhanced using preferentially oriented nitrogen-vacancy (NV ...

Modelling Rabi oscillations for widefield radiofrequency imaging in nitrogen-vacancy centers in diamond

New Journal of Physics
In this paper we study the dynamics of an ensemble of nitrogen-vacancy centers in diamond when its photoluminescence is detected by means of a widefield imaging system.

Coupling Nitrogen-Vacancy Centers in Diamond to Superconducting Flux Qubits [PDF]

Physical Review Letters, 2010
We propose a method to achieve coherent coupling between Nitrogen-vacancy (NV) centers in diamond and superconducting (SC) flux qubits. The resulting coupling can be used to create a coherent interaction between the spin states of distant NV centers mediated by the flux qubit.

Vibrational and electronic ultrafast relaxation of the nitrogen-vacancy centers in diamond

EPJ Web of Conferences, 2013
Two dimensional electronic spectroscopy and transient grating measurements were performed, for the first time, on nitrogen-vacancy centers in diamond. These measurements reveal energy transfer and vibrational pathways with consequences for spin coherence.

Terahertz emission from diamond nitrogen-vacancy centers

Science Advances
Coherent light sources emitting in the terahertz range are highly sought after for fundamental research and applications. Terahertz lasers rely on achieving population inversion. We demonstrate the generation of terahertz radiation using nitrogen-vacancy centers in a diamond single crystal.

Light dark matter search with nitrogen-vacancy centers in diamonds [PDF]

Journal of High Energy Physics
We propose an approach to directly search for light dark matter, such as the axion or the dark photon, by using magnetometry with nitrogen-vacancy centers in diamonds. If the dark matter couples to the electron spin, it affects the evolution of the Bloch

Robust nuclear hyperpolarization driven by strongly coupled nitrogen vacancy centers [PDF]

, 2021
Nuclear magnetic resonance techniques are widely used in the natural sciences but they lack sensitivity. Therefore, large sample volumes or long measurement times are necessary.

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.

TR12 centers in diamond as a room temperature atomic scale vector magnetometer

npj Quantum Information, 2022
The family of room temperature atomic scale magnetometers is currently limited to nitrogen-vacancy centers in diamond. However, nitrogen-vacancy centers are insensitive to strong off-axis magnetic fields.
