Towards a realistic description of the interplay of bosonic and fermionic degrees of freedom in the physical properties of Fe pnictide in the normal and superconducting state: multiband approaches with the account of disorder effects

由于具有较高的超导转变临界温度，Fe-硝基化合物引起了人们的极大兴趣。我们利用电子能谱、中子实验和密度泛函理论计算中的实际参数，从理论的角度研究了相关的丰富的电子相图，并讨论了电致发光相互作用、费米表面嵌套、电致发光耦合和无序的作用。我们计算了常态和超导态下多肽的热力学性质和输运性质。

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.
