Investigating the excitation spectrum of a single-band Hubbard model compound...

The single band Hubbard model is considerably the simplest effective model that includes both the delocalizing/hopping energy and the on-site interaction for describing strongly...单带哈伯德模型（Single band Hubbard model）堪称最为简洁的有效模型，其同时涵盖了离域/跳跃能与在位相互作用，可用于描述强关联……
