Among the diverse and ever-expanding array of approaches to the electronic structure
problem, the rise of approximate density functional theory (DFT) as the method of choice for …

Numerous correlated electron systems exhibit a strongly scale-dependent behavior. Upon
lowering the energy scale, collective phenomena, bound states, and new effective degrees …

Superconducting nickelates appear to be difficult to synthesize. Since the chemical
reduction of ABO 3 [rare earth (A), transition metal (B)] with CaH 2 may result in both ABO 2 …

We demonstrate how ab initio cluster calculations including the full Coulomb vertex can be
done in the basis of the localized Wannier orbitals which describe the low-energy density …

We present an implementation of an interface between the full-potential linearized
augmented plane wave package Wien2k and the wannier90 code for the construction of …

We study the effect of the lattice structure on the spin-fluctuation-mediated superconductivity
in the iron pnictides adopting the five-band models of several virtual lattice structures of …

We present an approach that combines the local-density approximation (LDA) and the
dynamical mean-field theory (DMFT) in the framework of the full-potential linear augmented …

Effective low-energy Hamiltonians for several different families of iron-based
superconductors are compared after deriving them from the downfolding scheme based on …

Narrow band materials (transition metals and rare‐earth elements compounds) often reveal
anomalous physical properties. Their electronic structure is strongly renormalized by …

Using the fluctuation-exchange approximation, we study an effective five-band Hubbard
model for iron-pnictide superconductors obtained from the first-principles band structure. We …
