Ab initio downfolding study of the iron-based ladder superconductor BaFeS
Ryotaro Arita, Hiroaki Ikeda, Shiro Sakai +1
Motivated by the recent discovery of superconductivity in the iron-based ladder compound BaFeS under high pressure, we derive low-energy effective Hamiltonians from first p…
First-principles study of magnetic properties in Fe-ladder compound BaFe2S3
Michi-To Suzuki, Ryotaro Arita, Hiroaki Ikeda
We study the magnetic, structural, and electronic properties of the recently discovered iron- based superconductor BaFe2S3 based on density functional theory with the generalized g…
Emergent loop-nodal s-wave superconductivity in CeCuSi: similarities to the iron-based superconductors
Hiroaki Ikeda, Michi-To Suzuki, Ryotaro Arita
Heavy-fermion superconductors are prime candidates for novel electron-pairing states due to the spin-orbital coupled degrees of freedom and electron correlations. Superconductivity…
