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…
Polarized nuclear target based on parahydrogen induced polarization
D. Budker, M. P. Ledbetter, S. Appelt +2
We discuss a novel concept of a polarized nuclear target for accelerator fixed-target scattering experiments, which is based on parahydrogen induced polarization (PHIP). One may be…
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…
