Исследование магнитных, нематических и сверхпроводящих свойств высокотемпературных сверхпроводников на основе железа методом вариационного кластерного приближения

Abstract

A class of high-temperature superconductors (HTSC) based on iron was discovered in 2008 [1]. Although more than nine years have elapsed since the discovery, an unambiguous microscopic theory explaining the complex phase diagrams of this class of superconductors has not yet been created [2]. This work is aimed at restoring the phase diagram of iron-based HTSC at zero temperature by variational cluster approximation [3].
