  • The origin of the nematic state in the kagome metal CsTi3Bi5 remains unclear. Here, using polarization-dependent angle-resolved photoelectron spectroscopy and ab initio based field theoretical methods, the authors propose a d-wave nematic order driven by electronic correlations via an orbital-selective mechanism.

  • Topological state in Kondo insulators has been provoked in SmB6, but the origin of surface states and topological order remain elusive. Here, Hagiwara et al. report temperature dependent reconstruction of a metallic surface state on the (001) surface of YbB12driven by Kondo effect and discuss its origin from topology.

  • Previous work exploring the robustness of topological surface states to perturbations has mostly focused on surfaces with the same atomic structure as the bulk. Here the authors demonstrate the effect of surface reconstruction on the topological surfaces on the (100) surface of SmB6.

  • Self-intercalated Chromium tellurides consist of CrTe2 van der Waals layers, with additional Chromium atoms residing in the van der Waals gap. This highly tuneable class of magnetic materials has presented a range of unique magnetic phenomena, and here Bigi, Jego, Polewczyk et al add to this by showing that CrTe2 (δ = 0.25 − 0.50) hosts orthogonal ferromagnetism.

  • Polymerization on surfaces is an emerging approach for producing graphene nanoribbons with a tunable bandgap, a promising material for carbon-based electronics. Here, Vasseur et al.show quasi-one-dimensional band structure of a model semiconducting polymer synthesized directly on a supporting surface.

  • Future spintronic devices may exploit spin-orbit interactions, which often emerge from broken symmetries and strongly influence electronic behaviour. Here, the authors evidence the amplification of Rashba coupling by a crystal field that breaks the local inversion symmetry at the Ni site in BaNiS2.
