    Controlling orbital magnetic moments for applications can be difficult. Now local probes of a kagome material, TbV6Sn6, demonstrate how the spin Berry curvature can produce a large orbital Zeeman effect that can be tuned with a magnetic field.

    Topologically protected hinge modes could be important for developing quantum devices, but electronic transport through those states has not been demonstrated. Now quantum transport has been shown in gapless topological hinge states.

    The electronic transport properties of charge-ordered kagome metals are controversial. Now careful measurements on unperturbed samples show that previously measured anisotropy in the transport occurs only when external perturbations are present.

    Observations of strong electron correlation effects have been mostly confined to compounds containing f orbital electrons. Now, the study of the 3d pyrochlore metal CuV2S4 reveals that similar effects can be induced by flat-band engineering.

    Electric polarization is well defined for insulators but not for metals. Electric-like polarization is now realized via inhomogeneous lattice strain in metallic SrRuO3, generating a pseudo-electric field. This field affects the material’s electronic bands.

    Using the valley degree of freedom in analogy to spin to encode qubits could be advantageous as many of the known decoherence mechanisms do not apply. Now long relaxation times are demonstrated for valley qubits in bilayer graphene quantum dots.

    In its superconducting state, MoTe2 displays oscillations arising from an edge supercurrent, and when it is near niobium, there is an incompatibility between electron pairs diffusing from niobium and the pairs intrinsic to MoTe2. Insight into this competition between pairs is obtained by monitoring the noise spectrum of the MoTe2 supercurrent oscillations.

    The Kondo effect — the screening of an impurity spin by conduction electrons — is a fundamental many-body effect. However, recent experiments combined with simulations have caused a long-standing model system for the single-atom Kondo effect to fail.

    Interactions between a localized magnetic moment and electrons in a metal can produce an emergent resonance that affects the metal’s properties. A realization of this Kondo effect in MoS2 provides an opportunity to study it in microscopic detail.

    Local thermodynamic measurements of a twisted transition metal dichalcogenide heterostructure reveal competition between unconventional charge order and Hofstadter states. This results from the presence of both flat and dispersive electronic bands, whose energetic ordering can be experimentally tuned.

    Measurements of the electronic structure of a trilayer cuprate superconductor suggest that its high critical temperature is explained by the different doping levels of the layers. The combination of underdoped inner layer and overdoped outer layers supports superconductivity.
