Magnetic-Field-Dependent Stimulated Emission from Nitrogen-Vacancy Centres in Diamond
F. Hahl, L. Lindner, X. Vidal +9
Negatively charged nitrogen-vacancy centres in diamond are promising quantum magnetic field sensors. Laser threshold magnetometry has been a theoretical approach for the improvemen…
Absorptive laser threshold magnetometry: combining visible diamond Raman lasers and nitrogen-vacancy centres
Sarath Raman Nair, Lachlan J. Rogers, David J. Spence +5
We propose a high-sensitivity magnetometry scheme based on a diamond Raman laser with visible pump absorption by an ensemble of coherently microwave driven negatively charged nitro…
Amplification by stimulated emission of nitrogen vacancy centres in a diamond-loaded fibre cavity
Sarath Raman Nair, Lachlan J. Rogers, Xavier Vidal +7
Laser-threshold magetometry using the negatively charged nitrogen-vacancy (NV-) centre in diamond as a gain medium has been proposed as a technique to dramatically enhance the sens…
The effects of thermal and correlated noise on magnons in a quantum ferromagnet
Jan Jeske, Ángel Rivas, Muhammad H. Ahmed +2
The dynamics and thermal equilibrium of spin waves (magnons) in a quantum ferromagnet as well as the macroscopic magnetisation are investigated. Thermal noise due to an interaction…
