Driven quadrature and spin squeezing in a cavity-coupled ensemble of two-level states
Haitham A. R. El-Ella
The generated magnitude of quadrature squeezing in a cavity-coupled ensemble, which is continuously driven using a coherent off-axis field, is theoretically explored. Using a trunc…
Observation of the Magneto-Optic Voigt Effect in a Paramagnetic Diamond Membrane
Haitham A. R. El-Ella, Kristian H. Rasmussen, Alexander Huck +2
The magneto-optic Voigt effect is observed in a synthetic diamond membrane with a substitutional nitrogen defect concentration in the order of 200 ppm and a nitrogen-vacancy defect…
Continuous microwave hole burning and population oscillations in a diamond spin ensemble
Haitham A. R. El-Ella, Alexander Huck, Ulrik L. Andersen
Continuous spectral hole burning and spin-level population oscillations are studied in an inhomogeneously broadened diamond-based spin ensemble composed of substitutional nitrogen…
Magnon Condensation in a Dense Nitrogen-Vacancy Spin Ensemble
Haitham A. R. El-Ella
The feasibility of creating a Bose-Einstein condensate of magnons using a dense ensemble of nitrogen-vacancy spin defects in diamond is investigated. Through assessing a density-de…
Clock transition by continuous dynamical decoupling of a three-level system
Alexander Stark, Nati Aharon, Alexander Huck +4
We present a novel continuous dynamical decoupling scheme for the construction of a robust qubit in a three-level system. By means of a clock transition adjustment, we first show h…
Nitrogen-Vacancy Ensemble Magnetometry Based on Pump Absorption
Sepehr Ahmadi, Haitham A. R. El-Ella, Adam M. Wojciechowski +4
We demonstrate magnetic field sensing using an ensemble of nitrogen-vacancy centers by recording the variation in the pump-light absorption due to the spin-polarization dependence…
