This book covers different aspects of the physics of iron-based superconductors ranging from
the theoretical the numerical and computational to the experimental ones. It starts from the
basic theory modeling many-body physics in Fe-superconductors and other multi-orbital materials
and reaches up to the magnetic and Cooper pair fluctuations and nematic order. Finally it
offers a comprehensive overview of the most recent advancements in the experimental
investigations of iron based superconductors.
