Chiral topological superconductivity in hole-doped Sn/Si(111)
Matthew Bunney, Lucca Marchetti, Domenico Di Sante +2
A third monolayer of tin atoms on the semiconductor substrate Si(111) has been shown to become superconducting upon six to ten percent hole doping. Experiments have reported promis…

Fractionalized Superconductivity Mediated by Majorana Fermions in the Kitaev-Kondo Lattice
Matthew Bunney, Urban F. P. Seifert, Stephan Rachel +1
Superconductivity usually emerges from a metallic normal state which follows the Fermi-liquid paradigm. If, in contrast, the normal state is a fractionalized non-Fermi liquid, then…

Electronic structure, spin-orbit interaction and electron-phonon coupling of triangular adatom lattices on semiconductor substrates
Lucca Marchetti, Matthew Bunney, Domenico Di Sante +1
A one-third monolayer of the heavy metals Sn and Pb deposited on semiconductor substrates can lead to a surface reconstruction, constituting an exciting tr…
