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…
Emergent Superconductivity and Competing Charge Orders in Hole-Doped Square-Lattice - Model
Xin Lu, Feng Chen, W. Zhu +2
The square-lattice Hubbard and closely related - models are considered as basic paradigms for understanding strong correlation effects and unconventional superconductivity (S…
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…
Ground-state phase diagram of the extended two-leg - ladder
Xin Lu, Dai-Wei Qu, Yang Qi +2
Inspired by the observation of a robust -wave superconducting phase driven by tuning the next-nearest-neighbor (NNN) electron hopping in recent density matrix renormalization gr…
