Delafossites as an unexpected competing phase to infinite-layer oxides
Armin Sahinovic, Benjamin Geisler, Rossitza Pentcheva
Motivated by the discovery of superconductivity in Sr-doped infinite-layer nickelate films on SrTiO(001), we explore the broader landscape of O oxides through comprehen…

Engineering the band structure of few-layer graphene by S-doping: from linear dispersion to impurity flat bands
Armin Sahinovic, Rossitza Pentcheva
Motivated by the technological relevance of S-doped few-layer graphene (FLG) in battery applications and in the oxygen reduction reaction, we systematically explore the effect of b…

Nature of the magnetic coupling in infinite-layer nickelates versus cuprates
Armin Sahinovic, Benjamin Geisler, Rossitza Pentcheva
In contrast to the cuprates, where the proximity of antiferromagnetism (AFM) and superconductivity is well established, first indications for AFM interactions in superconducting in…
