  • Electronic systems with inverted band structures can support exotic topological insulator and exciton condensate states. Here, the authors demonstrate the formation of a helical exciton condensate in quantum Hall bilayers, and a quark-like quasiparticle confinement-deconfinement transition.

  • Majorana bound states at the end of nanowires may be used for quantum computation if they can be coupled sufficiently strongly. Here, the Copenhagen lab show strong and tunable coupling, a step along the road towards devices.

  • A so-called Josephson ϕ0-junction based on a nanowire quantum dot is reported. By means of electrostatic gating, it is possible to controllably introduce a phase offset taking any value between 0 and π in the ground state of the junction.

  • Axial fields couple to the states of different chiralities with opposite signs. In an acoustic Weyl system, the implementation of such fields induces chiral Landau levels, which is now observed experimentally.
