  • Graphene exhibits many extraordinary properties. But, despite many attempts to find ways to induce it, superconductivity is not one of them. First-principles calculations suggest that by decorating the surface of graphene with lithium atoms, it could yet be made to superconduct.

  • Edge states of QSHIs hold promise for future technologies due to protection against backscattering. This work observes that intraband backscattering remains allowed for nonmonotonic edge bands, revealing critical aspects of edge state stability.

  • The search for near-ambient superconductivity in hydrides is hindered by the emergence of metastable phases during sample preparation. Tresca et al. predict that spontaneous formation of H2 molecules in N-doped LuH3 lead to dynamical stabilization, allowing low-temperature superconductivity at ambient pressure.

  • The incommensurate spin density wave of chromium is a classic example of itinerant antiferromagnetism induced by Fermi surface nesting. Here, the competing structural, electronic and magnetic orders in chromium are investigated by a joint soft-X-ray angle resolved photoemission spectroscopy and density functional theory study of its band structure.

  • The key role played by hydrogen (H) in the near-to-room temperature superconductivity of hydrides at megabar pressures suggests that H doping could produce similar effects in materials at ambient pressure. Here the authors show that ionic gate-driven H intercalation in the layered compound TiSe2 induces a superconducting phase with features distinct from those obtained through other doping techniques.
