Intrinsic versus extrinsic orbital and electronic reconstructions at complex oxide interfaces
R. J. Green, V. Zabolotnyy, M. Zwiebler +10
The interface between the insulators LaAlO and SrTiO accommodates a two-dimensional electron liquid (2DEL) -- a high mobility electron system exhibiting superconductivity a…
Electronic Structure of the Bond Disproportionated Bismuthate AgBiO
Mohamed Oudah, Minu Kim, Ksenia S. Rabinovich +11
We present a comprehensive study on the silver bismuthate AgBiO, synthesized under high-pressure high-temperature conditions, which has been the subject of recent theoretic…
LiNiO as a high-entropy charge- and bond-disproportionated glass
Kateryna Foyevtsova, Ilya Elfimov, Joerg Rottler +1
Understanding microscopic properties of LiNiO, a Li-ion battery cathode material with extraordinarily high reversible capacity, has remained a challenge for decades. Based on e…
Holes' character and bond versus charge disproportionation in perovskites
Mohammad Reza Benam, Kateryna Foyevtsova, Arash Khazraie +2
We use density functional theory methods to study the electronic structures of a series of cubic perovskites : the experimentally available SrBiO, BaBiO,…
Multiple-magnon excitations shape the spin spectrum of cuprate parent compounds
Davide Betto, Roberto Fumagalli, Leonardo Martinelli +12
Thanks to high resolution and polarization analysis, resonant inelastic x-ray scattering (RIXS) magnetic spectra of La2CuO4, Sr2CuO2Cl2 and CaCuO2 reveal a rich set of properties o…
