Multi-band Hubbard Model Simulation for Unconventional Superconducting System*

To simulate the new experiment findings on unconventional superconductor materials such as Cuprates and iron pnictides, it is inevitable to go beyond single-band model and capture the physics from multi-band effects. We carried out a novel Dynamical Cluster Quantum Monte Carlo study on multi-band Hubbard model, implementing the Continuous Time Quantum Monte Carlo algorithm as quantum solver. We studied various of single-particle properties aiming to observe the experiment concerned issues such as the spontaneous symmetry breaking to nematic order.
