講演要旨:

One of the most wealth fields in condensed matter physics is a kind of strongly correlated quantum systems where many-body interactions dominate determining fundamental physical properties. These systems include Hubbard-like models and frustrated quantum spin models, which are relevant, for example, to high-Tc cuprate superconductors and quantum spin liquids. The widely accepted consensus is that there is no ultimate numerical method at the present to solve a reasonably wide range of strongly correlated quantum systems in spatial dimensions higher than one dimension. In this talk, I will first explain what strongly correlated materials are and why we do have to care, and then introduce some of our team research activities, mostly focusing on quantum Monte Carlo and density matrix renormalization group simulations.
