Global Network of Optical Magnetometers for Exotic (GNOME): Physics Novel scheme for exotic physics searches
S. Pustelny, D. F. Jackson Kimball, C. Pankow +8
A novel experimental scheme enabling investigation of transient exotic spin couplings is discussed. The scheme is based on synchronous measurements of optical-magnetometer signals…
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…
Constraints on short-range spin-dependent interactions from scalar spin-spin coupling in deuterated molecular hydrogen
Micah Ledbetter, Michael Romalis, Derek Jackson-Kimball
A comparison between existing measurements and calculations of the scalar spin-spin interaction (J-coupling) in deuterated molecular hydrogen (HD) yields stringent constraints on a…
Liquid-state nuclear spin comagnetometers
Micah Ledbetter, Szymon Pustelny, Dmitry Budker +3
We discuss nuclear spin comagnetometers based on ultra-low-field nuclear magnetic resonance in mixtures of miscible solvents, each rich in a different nuclear spin. In one version…
Detection of a single cobalt microparticle with a microfabricated atomic magnetometer
Daniel Maser, Saurabh Pandey, Hattie Ring +4
We present magnetic detection of a single, 2 μm diameter cobalt microparticle using an atomic magnetometer based on a microfabricated vapor cell. These results represent an improve…
Near-zero-field nuclear magnetic resonance
Micah Ledbetter, Thomas Theis, John Blanchard +6
We investigate nuclear magnetic resonance (NMR) in near-zero-field, where the Zeeman interaction can be treated as a perturbation to the electron mediated scalar interaction (J-cou…
