What is the orbital diagram for iron? What are the four quantum numbers for each of the two electrons in a 4s orbital? What is an electronic orbital? What is the maximum number of electrons that can occupy the 2s orbital? What is the difference between an orbital and an energy level?
The phase diagram of the two-dimensional two-orbital Hubbard model, which is widely used to describe high-temperature iron-based superconductors, is calculated in the electron doping region using the method of the variational cluster approximation. It is found that the coexistence of the ...

The underdoped phase diagram of the iron-based superconductors exemplifies the complexity common to many correlated materials. Indeed, multiple ordered states that break different symmetries but display comparable transition temperatures are present. Here, we argue that such a complexity can be understood...
