Quantum formulation of the Einstein equivalence principle, Published online: 13 August 2018; doi:10.1038/s41567-018-0197-6

The physical conditions that support a geometric interpretation of spacetime, such as the equivalence between rest and inertial mass, are shown not to be necessarily valid in the quantum regime, and a quantum formulation is provided.

Routing the emission of a near-surface light source by a magnetic field, Published online: 06 August 2018; doi:10.1038/s41567-018-0232-7

The Kerr and Faraday effects enable routing of light in an applied magnetic field. Now a new class of magneto-optical phenomena is proposed and demonstrated in which light emission is controlled perpendicular to the external magnetic field.

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.

The properties of bismuth have long defied expectation, casting it just outside the bounds of almost every category. Now topology joins the list, as its electronic structure once deemed trivial turns out to have higher-order topology.
