Speaker: Dr. Min LIU (Caltech)
In this talk, I will discuss our traditional Dynamical Mean-Field Theory (DMFT) calculations on the quadruple-perovskite CaCu3Ir4O12, in which we proposed a symmetry-based mechanism that may enforce heavy-fermion physics. Then I will talk about an efficient DMFT framework from a quantum chemical perspective, which is fully ab initio, double counting free and capable of treating about 100 impurity orbitals. In particularly, I will introduce the real-time couple cluster solver I developed and discuss its future applications.
