Fe-pnictides are of large interest due to high critical temperature of superconductive transition. We study the related rich electronic phase diagrams from a theoretical point of view, using models with realistic parameters from electron spectroscopy, neutron experiments and DFT calculations and address the role of el-el interaction, Fermi-surface nesting, el-ph coupling, and disorder. We calculate thermodynamic and transport properties of pnictides in the normal and superconducting states.

铁磷属化合物由于其高的相变临界温度而引起人们的极大兴趣。我们研究了相关的丰富的电子相图从理论的角度来看，使用模型与现实的参数，从电子光谱，中子实验和DFT计算和地址的作用，EL-EL相互作用，费米面嵌套，EL-PH耦合，和无序。计算了磷属元素化物在正常态和超导态下的热力学和输运性质。
