Global Phase Diagram of D-wave Superconductivity in the Square-Lattice $t\text{-}J$ Model

Feng Chen, F. D. M. Haldane, D. N. Sheng

The Hubbard and closely related $t\text{-}J$ models are exciting platforms for unconventional superconductivity (SC). Through state-of-the-art density matrix renormalization group ca…
