First-principles calculation of transition-metal impurities in LaFeAsO
Kazuma Nakamura, Ryotaro Arita, Hiroaki Ikeda
We present a systematic ab initio study based on density-functional calculations to understand impurity effects in iron-based superconductors. Effective tight-binding Hamiltonians…
Ab initio Low-Dimensional Physics Opened Up by Dimensional Downfolding: Application to LaFeAsO
Kazuma Nakamura, Yoshihide Yoshimoto, Yoshiro Nohara +1
An ab initio downfolding method is formulated to construct low-dimensional models for correlated electrons. In addition to the band downfolding by constrained random phase approxim…
Magnetic Properties of Ab initio Model for Iron-Based Superconductors LaFeAsO
Takahiro Misawa, Kazuma Nakamura, Masatoshi Imada
By using variational Monte Carlo method, we examine an effective low-energy model for LaFeAsO derived from an ab initio downfolding scheme. We show that quantum and many-body fluct…
