  • Electron-electron interactions in many-body systems may manifest themselves through the fractional quantum Hall effect. Here, the authors perform transport measurements in bilayer graphene, and observe particle-hole symmetric fractional quantum Hall states in theN=2 Landau level.

  • Electric fields can controllably break the inversion symmetry of bilayer graphene, which can be harnessed to generate pure valley currents.

  • Graphene can exhibit pronounced frictional anisotropy, which was thought to arise because of nanoscale ripples. Here, the authors provide evidence that this effect could instead be a result of adsorbates that self-assemble into a highly regular superlattice of stripes with a period of four to six nanometres.

  • The interface between a quantum Hall state and a superconductor hosts topological modes. Here, interference between two such modes turns an electron into either a hole or an electron depending on the phase difference along the interference path.
