Competing and Intertwined Orders in Boson-Doped Mott Antiferromagnets
Xin Lu, Jia-Xin Zhang, Lukas Homeier +3
Inspired by the recent experimental advances in cold atom quantum simulators, we explore the experimentally implemented bosonic -- model on the square lattice using large…

Tuning competition between charge order and superconductivity in the square-lattice -- model
Xin Lu, Huaiming Guo, Wei-Qiang Chen +2
Recently, a flurry of works have found strong competition between charge density wave (CDW) and superconductivity (SC) in the doped Hubbard and - models on the square lattice…

Sign structure of the -- model and its physical consequences
Xin Lu, Jia-Xin Zhang, Shou-Shu Gong +2
Understanding the doped Mott insulator is a central challenge in condensed matter physics. In this work, we first explicitly identify a new sign structure in the -- model…
