  Magnetometry goes nuclear

  Quantum sensing that uses electron spins in diamond can perform precise magnetic field measurements but does not work well at high magnetic fields. An alternative approach involving the spins of carbon-13 nuclei can operate in the high-field regime.

  Experiments with levitated force sensor challenge theories of dark energy

  In experiments with a levitated force sensor, no signatures of a fifth force are detected. This rules out the basic chameleon model, which is a popular theory providing an explanation for dark energy.

  Cool sensing

  Superconducting quantum interference devices can accurately measure temperatures even below 1 mK, but there’s more to them — as Thomas Schurig explains.

  Charge quantum interference device

  The charge–phase duality in superconductors implies that the well-known SQUID has an analogue based on the interference of fluxons. Such a ‘charge quantum interference device’ (or CQUID) has now been experimentally demonstrated.

  Magnetic pseudo-fields in a rotating electron–nuclear spin system

  Physical rotation can create fictitious magnetic fields, a phenomenon that stems from Larmor's theorem. The effect on a nuclear spin ensemble was measured using the spin–echo of nitrogen–vacancy centres in rapidly spinning diamond. Interestingly, the rotationally induced magnetic fields can cancel a conventional magnetic field for the nuclear spins.
