On-site-interaction-induced Peak-dip-hump Characteristics with the Mean Field Theory + Perturbation Approach
Xing Yang
For decades, the difficulty of tackling a strong coupling model with a perturbative approach remained regardless of numerous inquiries. In the current work, a typical mean field th…
