Proximity of antiferromagnetism and superconductivity in LaOFFeAs: effective Hamiltonian from ab initio studies
Chao Cao, P. J. Hirschfeld, Hai-Ping Cheng
We report density functional theory calculations for the parent compound LaOFeAs of the newly discovered 26K Fe-based superconductor LaOFFeAs. We find that the ground s…

Determining gap nodal structures in Fe-based superconductors: angle-dependence of the low temperature specific heat in an applied magnetic field
S. Graser, G. R. Boyd, Chao Cao +3
Since the discovery of high-Tc LaO_1-xF_xFeAs, and other such systems based on FeAs layers, several proposals have been made for the superconducting order parameter Delta_k, on bot…

Strongly Correlated Electrons in the Single Molecule Magnet: A DFT+U Study
Chao Cao, Stephen Hill, Hai-Ping Cheng
The single-molecule magnet is studied using both density functional theory (DFT) and the DFT+U method, and the results are compared. By incorporating…
