Tuning competition between charge order and superconductivity in the square-lattice $t$ - $t^{'}$ - $J$ 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 $t$ - $J$ models on the square lattice…

Origin of the Diagonal Double-Stripe Spin-Density-Wave and Potential Superconductivity in Bulk La $_{3}$ Ni $_{2}$ O $_{7}$ at Ambient Pressure

Yu-Bo Liu, Hongyi Sun, Ming Zhang +3

The discovery of high-temperature superconductivity (SC) with $T_{c} \approx 80$ K in the pressurized La $_{3}$ Ni $_{2}$ O $_{7}$ has aroused great interests. Currently, due to technical diff…
