Abstract
The Hubbard model is a fundamental to understand cuprates. Although the model has been extensively studied in the past decades, the precise understanding of the ground state is still challenging. Thanks to the recent development on the numerical techniques, we are now able to perform unbiased simulation and understand the low-energy states in a new level of energy resolution. In this talk I will briefly introduce some most powerful numerical techniques for the strong correlated systems, and discuss our recent work on the doped Hubbard model. In particular I will discuss the competition between the stripes and superconductivity orders. I will also give an example about another applications, including the understanding of topological superconductor and possibility to realize the topological quantum computing.
