Closed-contour spin driving

Coherent driving of all transitions of a three-level system generates a closed-contour interaction, which is here shown to create efficient manipulation methods for electronic spins in nitrogen–vacancy centres in diamond.

    Building spinning microrotors that self-assemble and synchronize to form a gear sounds like an impossible feat. However, it has now been achieved using only a single type of building block — a colloid that self-propels.

    The entropy of a few-electron quantum system is measured for the first time by tracking the movement of charge in and out of the system. This could allow the unambiguous detection of Majorana fermions in solid state devices.

    Surprising phenomena are known to occur when magnetic systems are confined to low-dimensional geometries. A resonant X-ray scattering study of NdNiO3 slabs reveals a crossover between different magnetic ground states as a function of thickness.

    Electrical transport measurements reveal that Co3Sn2S2 is probably a magnetic Weyl semimetal, and hosts the highest simultaneous anomalous Hall conductivity and anomalous Hall angle. This is driven by the strong Berry curvature near the Weyl points.
