Superconductivity in high-$T_c$ and related strongly correlated systems from variational perspective: Beyond mean field theory

Józef Spałek, Maciej Fidrysiak, Michał Zegrodnik +1

In this review, we single out selected universal features of high-$T_c$ and related systems, which can be compared with experiment. We start with the concept of real-space pairing,…
