Super spins, Published online: 11 June 2018; doi:10.1038/s41567-018-0182-0

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.

Long-distance spin transport through a graphene quantum Hall antiferromagnet, Published online: 11 June 2018; doi:10.1038/s41567-018-0161-5

Spins are transmitted over a distance of 5 μm through a piece of antiferromagnetic graphene. This shows that graphene can be a platform to explore the fundamental physics of spin transport in antiferromagnets for application in spintronics.

Equilibrium free energies from non-equilibrium trajectories with relaxation fluctuation spectroscopy, Published online: 28 May 2018; doi:10.1038/s41567-018-0153-5

Non-equilibrium physics grants access to equilibrium free energies from the work performed on fluctuating systems—but only when the work itself is measurable. Relaxation fluctuation spectroscopy provides an alternative route to these energies.

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.
