Solid-state electronic spin coherence time approaching one second
Nir Bar-Gill, Linh M. Pham, Andrejs Jarmola +2
Solid-state electronic spin systems such as nitrogen-vacancy (NV) color centers in diamond are promising for applications of quantum information, sensing, and metrology. However, a…
Sidebands in Optically Detected Magnetic Resonance Signals of Nitrogen Vacancy Centers in Diamond
Maria Simanovskaia, Kasper Jensen, Andrey Jarmola +3
We study features in the optically detected magnetic resonance (ODMR) signals associated with negatively charged nitrogen-vacancy (NV) centers coupled to other paramagnetic impurit…
Bulk Nuclear Polarization Enhanced at Room-Temperature by Optical Pumping
Ran Fischer, Christian O. Bretschneider, Paz London +3
Bulk 13C polarization can be strongly enhanced in diamond at room-temperature based on the optical pumping of nitrogen-vacancy color centers. This effect was confirmed by irradiati…
Light narrowing of magnetic resonances in ensembles of nitrogen-vacancy centers in diamond
K. Jensen, V. M. Acosta, A. Jarmola +1
We investigate optically detected magnetic resonance signals from an ensemble of nitrogen-vacancy centers in diamond. The signals are measured for different light powers and microw…
A Remotely Interrogated All-Optical Rb Magnetometer
Brian Patton, Oscar Versolato, D. Chris Hovde +3
Atomic magnetometry was performed at Earth's magnetic field over a free-space distance of ten meters. Two laser beams aimed at a distant alkali-vapor cell excited and detected the…
Controllable steep dispersion with gain in a four-level N-scheme with four-wave mixing
Nathaniel B. Phillips, Irina Novikova, Eugeniy E. Mikhailov +2
We present a theoretical analysis of the propagation of light pulses through a medium of four-level atoms, with two strong pump fields and a weak signal field in an N-scheme arrang…
How do you know if you ran through a wall?
M. Pospelov, S. Pustelny, M. P. Ledbetter +3
Stable topological defects of light (pseudo)scalar fields can contribute to the Universe's dark energy and dark matter. Currently the combination of gravitational and cosmological…
Gyroscopes based on nitrogen-vacancy centers in diamond
Micah Ledbetter, Kasper Jensen, Ran Fischer +2
We propose solid-state gyroscopes based on ensembles of negatively charged nitrogen-vacancy () centers in diamond. In one scheme, rotation of the nitrogen-vacancy symme…
Optical polarization of nuclear ensembles in diamond
Ran Fischer, Andrey Jarmola, Pauli Kehayias +1
We report polarization of a dense nuclear-spin ensemble in diamond and its dependence on magnetic field and temperature. The polarization method is based on the transfer of electro…
Room Temperature Operation of a Radiofrequency Diamond Magnetometer near the Shot Noise Limit
Chang S. Shin, Claudia E. Avalos, Mark C. Butler +8
We operate a nitrogen vacancy (NV-) diamond magnetometer at ambient temperatures and study the dependence of its bandwidth on experimental parameters including optical and microwav…
