In this Comment, using Korringa-Kohn-Rostoker coherent-potential approximation method in the atomic-sphere approximation (KKR-ASA CPA) to describe the effects of disorder due to excess Fe in FeTe alloys, we show that (i) the rigid-band approximation is inadequate to describe the effects of disorder and its application leads to an incorrect description of the underlying physics, (ii) the rigid-band energy shift of ~0.76 eV for going from FeTe to Fe_{1.068}Te (or Fe_{1.063}Te), as obtained by Han and Savrasov (Phys. Rev. Lett. 103, 067001(2009)), is inconsistent with our FP-LMTO as well as the KKR-ASA results, and thus the FS of Fe_{1.063}Te shown in Fig. 3(b) of their paper is not correct.
Unusual Fermi surface nesting in parent compounds of iron arsenic high temperature superconductors revealed by Angle Resolved Photoemission Spectroscopy
本文用相干势近似研究了FeSe中Fe的过量、Se的缺乏以及S、Te对Se亚晶格的替代和Co、Ni、Cu对Fe亚晶格的替代的影响。结果表明：（i）少量过量Fe使Fe导带发生无序化，而Se的缺乏主要影响Se导带;（ii）S或Te的替代增强了费米面嵌套的可能性，特别是在FeSe $_{0.5}$ Te $_{0.5}$中，尽管Se导带发生无序化;（iii）Co的电子掺杂，Ni或Cu使系统紊乱并向下推Fe衍生带，从而破坏费米表面嵌套的可能性。这些结果与刚性带，虚拟晶体和超原胞近似的比较揭示了与相干势近似描述无序的重要性。

Doping-type-dependent pairing symmetry in predicted Ni-based high-$T_c$ superconductor La$_2$Ni$_2$Se$_2$O$_3$
在无规相位近似下研究了新预测的镍基高$T_c$超导材料La $_2$ Ni $_2$ Se $_2$ O $_3$的电子不稳定性.我们对磁化率的计算表明，母体化合物中的共线反铁磁态是由完美的费米面嵌套引起的。进一步的计算表明，掺杂化合物的基态是由准嵌套增强的反铁磁自旋涨落驱动的$s_{\pm}$和$d_{xy}$波超导态。有趣的是，$s$和$d$波配对分别发生在空穴和电子掺杂的情况下。这种对对称性的掺杂类型依赖性可以从嵌套费米口袋的掺杂依赖性来理解。
