Topologically trivial and Majorana bound states can show spectral weight near the ends of a chain of magnetic atoms on a superconductor. Here, the authors disentangle the two contributions by augmenting a spin chain with orbitally-compatible nonmagne

Scanning tunnelling microscopes can be used to accurately position atoms and measure emergent behaviour arising from interatomic couplings. Here, the authors fabricate a model spin chain and show the formation of a tunable spiral state due to competi

Chains of magnetic atoms with either strong spin-orbit coupling or spiral magnetic order which are proximity-coupled to superconducting substrates can host topologically non-trivial Majorana bound states. The experimental signature of these states co

Non-collinear spin states with unique rotational sense, such as chiral spin-spirals, are recently heavily investigated because of advantages for future applications in spintronics and information technology and as potential hosts for Majorana Fermion

Spins of single atoms adsorbed on substrates are promising building blocks for spintronics and quantum computation schemes. To process spin information and for increased magnetic stability, these spins have to be coupled to arrays. For a single atom,
