Superconductivity has been discovered recently in infinite-layer nickel-based 112 thin films
R 1− x A x NiO 2 (R= La, Nd, Pr and A= Sr, Ca). They are isostructural to the infinite-layer …

Metal-insulator transitions are accompanied by huge resistivity changes, even over tens of
orders of magnitude, and are widely observed in condensed-matter systems. This article …

A generalization of the local density approximation (LDA) method for systems with strong
Coulomb correlations is described which gives a correct description of the Mott insulators …

This article reviews the physics of high-temperature superconductors from the point of view
of the doping of a Mott insulator. The basic electronic structure of cuprates is reviewed …

Although the vast majority of high-T c cuprate superconductors are hole-doped, a small
family of electron-doped compounds exists. Underinvestigated until recently, there has been …

Simulating strongly correlated fermionic systems is notoriously hard on classical computers.
An alternative approach, as proposed by Feynman, is to use a quantum computer. We …

Oxygen K-edge absorption spectra of carefully characterized La 2− x Sr x CuO 4+ δ samples
were measured using a bulk-sensitive fluoresence-yield-detection method. They reveal two …

We present results of local spin density approximation (LSDA) pseudopotential calculations
for the perovskite structure oxide, bismuth manganite (BiMnO 3). The origin of the …

We derive the effective single-band Hamiltonian in the flat NiO 2 planes for nickelate
compounds Nd 1− x Sr x NiO 2. We implement the first-principles calculation to study …

A theoretical review is given on high temperature superconductivity in copper oxides
(cuprates) by focusing on the hole doping cases based on the view that it is realized in …
