    Applications of spintronics often require angular momentum to be moved from place to place. A possible observation of spin superfluidity may point the way toward the transport of spin angular momentum across an insulating sample with no dissipation or energy loss.

    The ideas of topology are breaking ground in origami-based metamaterials. Experiments now show that certain shapes — doughnuts included — exhibit topological bistability, and can be made to click between different topologically stable states.

    The first campaign of the largest stellarator ever built, Wendelstein 7-X, has been successful, achieving high electron temperatures and minimal self-generated plasma current. This is very encouraging for future long-pulse, full-power operation.

    Many-body quantum systems fail to reach thermalization only under specific circumstances. An analysis now reveals a new, different kind of non-equilibrating dynamics based on the many-body analogue of quantum scars in single-particle quantum chaos.
