Understanding the mechanism of high-Tc superconductivity is one of the grand challenges for condensed matter physics. In this talk, I will present density matrix renormalization group studies of an extended t-J model, which reveal the possible superconductivity states in the doped Mott insulator. In particular, we will demonstrate a quantum phase diagram including three phases: a stripe charge density wave phase, a uniform superconducting phase, and a superconducting phase coexistent with a weak charge stripe order. These findings reveal that enhanced charge and spin fluctuations with optimal doping are able to produce robust d-wave superconductivity in doped Mott insulators, providing a foundation for connecting theories of superconductivity to models of strongly correlated systems.
