Pressure-induced spin-state ordering in Sr $_{2}$ CoO $_{3}$ F

Juan Fernández Afonso, Andrii Sotnikov, Atsushi Hariki +1

We study theoretically low-temperature phases of a recently synthesized compound Sr $_{2}$ CoO $_{3}$ F under pressure. The analysis combining LDA+DMFT and a strong-coupling effective mode…

Chemical pressure effect on the optical conductivity of the nodal-line semimetals ZrSi $Y$ ( $Y$ =S, Se, Te) and ZrGe $Y$ ( $Y$ =S, Te)

J. Ebad-Allah, J. Fernández Afonso, M. Krottenmüller +5

ZrSiS is a nodal-line semimetal, whose electronic band structure contains a diamond-shaped line of Dirac nodes. We carried out a comparative study on the optical conductivity of Zr…

Theoretical investigation of excitonic magnetism in LaSrCoO $_{4}$

J. Fernández Afonso, A. Sotnikov, J. Kuneš

We use the LDA+U approach to search for possible ordered ground states of LaSrCoO $_{4}$ . We find a staggered arrangement of magnetic multipoles to be stable over a broad range of Co…

Excitonic magnetism in $d^{6}$ perovskites

J. Fernandez Afonso, J. Kunes

We use the LDA+U method to study the possibility of exciton condensation in perovskites of transition metals with $d^{6}$ electronic configuration such as LaCoO $_{3}$ . For realistic in…

Ab initio study of nontrivial topological phases in corundum structured $($ M $_{2}$ O $_{3}) / ($ Al $_{2}$ O $_{3})_{5}$ multilayers

Juan F. Afonso, Victor Pardo

\textit{Ab initio} calculations have been performed on hexagonal layers of M $_{2}$ O $_{3}$ (M being several transition metals of the $5 d$ series) sandwiched by a band insulator such as…
