  • The anomalous Hall effect (AHE) occurs in ferromagnets caused by intrinsic and extrinsic mechanisms. Here, Yoo et al. report large anomalous Hall conductivity and Hall angle at the interface between a ferromagnet La0.7Sr0.3MnO3 and a semimetallic SrIrO3, due to the interplay between correlated physics and topological phenomena.

  • Higher order topological systems extend the features of topological insulators from gapless surfaces states to more exotic phenomena such as corner and hinge states. Here, the authors investigate the effect of topology on superconductivity in a dice lattice showing that it can house a second-order topological phase with mixed singlet-triplet pairing and zero-energy Majorana corner states.

  • Flat bands are dispersionless electronic structures with increased electron–electron correlations and can coexist with the non-trivial topological features of a Kagome lattice. Here, the authors theoretically explore the interplay between band topology and electronic correlations in a multiorbital model on a Kagome lattice demonstrating that fractional filling can give rise to fractional Chern insulating states.

  • Majorana fermions are elusive particles which have proven extremely tricky to observe experimentally, with current efforts focused on hybrid superconducting devices. Here, the authors theoretically propose a set up combining a Josephson junction and a skyrmion crystal to create and control the Majorana bound states.

  • Understanding the spin-wave excitations of chiral magnetism is important to confirm such exotic magnetic order. Here, the authors obtain the spin wave spectrum for a given magnetic structure from Monte Carlo simulations and analyse the signatures when a ferromagnetic film undergoes a transition from a skyrmion crystal to a helical phase.
