Anharmonicity and structural phase transition in the Mott insulator Cu $_{2}$ P $_{2}$ O $_{7}$

Svitlana Pastukh, Paweł T. Jochym, Oleksandr Pastukh +3

Ab initio investigations of structural, electronic, and dynamical properties of the high-temperature $β$ phase of copper pyrophosphate were performed using density functional theor…

Influence of $f$ Electrons on the Electronic Band Structure of Rare-Earth Nickelates

Andrzej Ptok, Surajit Basak, Przemysław Piekarz +1

Recently, superconductivity was discovered in the infinite layer of hole-doped nickelates NdNiO $_{2}$ . Contrary to this, superconductivity in LaNiO $_{2}$ is still under debate. Thi…

Raman Active High Energy Excitations in URu $_{2}$ Si $_{2}$

Jonathan Buhot, Yann Gallais, Maximilien Cazayous +5

We have performed Raman scattering measurements on URu $_{2}$ Si $_{2}$ single crystals on a large energy range up to $\sim$ 1300 cm $^{- 1}$ and in all the Raman active symmetries as a fun…

Influence of isolated and clustered defects on electronic and dielectric properties of wustite

Urszula D. Wdowik, Przemyslaw Piekarz, Pawel T. Jochym +2

The influence of intrinsic Fe defects in FeO (either single cation vacancies or prototypical 4:1 vacancy clusters) on the electronic and dielectric properties is studied within the…

Comparative study of the electronic structures of Fe3O4 and Fe2SiO4

P. Piekarz, A. M. Oleś, K. Parlinski

The electronic properties of two spinels Fe $_{3}$ O $_{4}$ and Fe $_{2}$ SiO $_{4}$ are studied by the density functional theory. The local Coulomb repulsion $U$ and the Hund's exchange $J$ bet…
