Possible superconductivity in the electron-doped chromium pnictide LaOCrAs
Possible superconductivity in the electron-doped chromium pnictide LaOCrAs
We constructed an effective tight-binding model with five Cr $3d$ orbitals for LaOCrAs according to first-principles calculations. Basing on this model, we investigated possible superconductivity induced by correlations in doped LaOCrAs using the functional renormalization group (FRG). We find that there are two domes of superconductivity in electron-doped LaOCrAs. With …
