(https://journals.aps.org/prx/abstract/10.1103/PhysRevX.7.041034) The paper , titled "Search for Axionlike Dark Matter through Nuclear Spin Precession in Electric and Magnetic Fields," appeared Tuesday in the journal Physical Review X.
Many of us could name a handful of Spanish varieties quite easily, like Tempranillo, Garnacha, Monastrell, but cross the border and other than Touriga Nacional most of us would be making the nuclear spin tomograph light up like a Christmas tree.
Pauli first postulated that the atomic nucleus has a non-zero angular momentum (nuclear spin), (11) which would provide hyperfine structure due to a magnetic dipole interaction in addition to that due to nuclear field effects (electric quadrupole interaction).

Part three concerns the use of Mossbauer spectra in studying phenomena related to nuclear spin states and the effects on the structures of compounds.
Finally, we have found that a Mosbauer nucleus might be a good processor of the DQC1 algorithm while a nuclear spin chains quantum device would not be efficient for the calculation of [tau].
Additional magnetic field pulses were used to tilt the direction of the nuclear spin and create the superposition states.
"Thirty-nine minutes may not seem very long but as it only takes one-hundred-thousandth of a second to flip the nuclear spin of a phosphorus ion -- the type of operation used to run quantum calculations -- in theory over 20 million operations could be applied in the time it takes for the superposition to naturally decay by one percent," said Stephanie Simmons of Oxford University, an author of the paper in the U.S.

In the case of oxygen, however, the only stable odd-numbered isotope ([sup.17]O) has a nuclear spin that is quadropolar, rather than dipolar, as is the case for [sup.1]H, [sup.13]C, and [sup.15]N.
John Morton at Oxford University and others, has successfully generated and detected quantum entanglement between electron spin and nuclear spin in phosphorus impurities added to silicon.
Among specific topics are experimental characterizations of nuclear spin interaction tensors, symmetry effects at the local level, indirect coupling and connectivity, tensor interplay, intermolecular interactions and structural motifs, and structural biology.
