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…
Chern number landscape of spin-orbit coupled chiral superconductors
Matthew Bunney, Jacob Beyer, Ronny Thomale +2
Chiral superconductors are one of the predominant quantum electronic states of matter where topology, symmetry, and Fermiology intertwine. This is pushed to a new limit by further…
Van-Hove tuning of Fermi surface instabilities through compensated metallicity
Hendrik Hohmann, Matteo Dürrnagel, Matthew Bunney +6
Van-Hove (vH) singularities in the vicinity of the Fermi level facilitate the emergence of electronically mediated Fermi surface instabilities. This is because they provide a momen…
Competition of First-Order and Second-Order Topology on the Honeycomb Lattice
Matthew Bunney, Tomonari Mizoguchi, Yasuhiro Hatsugai +1
We investigate both first-order topology, as realized through Haldane's model, and second-order topology, implemented through an additional Kekulé-distortion, on the honeycomb latt…
