| 中文摘要 | We investigate the nonresonant Raman response for iron-based superconductors using the framework of an effective S-4 model that was recently proposed to capture the essential electronic and magnetic properties of iron-based superconductors. We compute the momentum matrix elements and the resulting Raman vertices exactly for different polarization geometries and find that a simple cos k(x) cos k(y) superconducting gap function is in good agreement with experimental data measured in both iron pnictides and iron chalcogenides. The Raman peaks are also matched quantitatively with the measured superconducting gaps by other experimental techniques. The result strengthens the validity of the S-4 model and the dominance of the s-wave pairing for iron-based superconductors. |
