Strong Coupling between a Single NV Spin and the Rotational Mode of Diamonds Levitating in an Ion Trap
arXiv:1702.00774 · doi:10.1103/PhysRevA.96.063810
Abstract
A scheme for strong coupling between a single atomic spin and the rotational mode of levitating nanoparticles is proposed. The idea is based on spin read-out of NV centers embedded in aspherical nanodiamonds levitating in an ion trap. We show that the asymmetry of the diamond induces a rotational confinement in the ion trap. Using a weak homogeneous magnetic field and a strong microwave driving we then demonstrate that the spin of the NV center can be strongly coupled to the rotational motion of the diamond.
New version with a focus on the strong coupling. "Torsional" has also been changed to "rotational"
