Interfacial Strain Modulated Correlated Plasmons in La1.85Sr0.15CuO4 and Their Role in High-temperature Superconductivity
Xiongfang Liu, Shengwei Zeng, Xun Liu +9
High-temperature superconductivity in cuprate materials remains a major challenge in physics due to the complexity of their strongly correlated electronic states. Interfacial strai…
Checkerboard-type Zhang-Rice States in Overdoped Cuprate Superconductors
Xiongfang Liu, Kun Han, Yan Peng +13
Cuprate superconductors remain central to condensed matter physics due to their technological relevance and unconventional, incompletely understood electronic behavior. While the c…
Superconductivity in imbalanced bilayer Hubbard model: enhanced -wave and weakened -wave pairing
Ziying Jia, Xun Liu, Mi Jiang
We investigate the bilayer model with two layers of imbalanced densities coupled by the interlayer hybridization. Using the large-scale dynamical cluster quantum Monte Carlo simula…
Enhanced superconductivity via layer differentiation in trilayer Hubbard model
Xun Liu, Mi Jiang
Motivated by the highest superconducting transition temperature () in multilayer cuprates,we investigated the trilayer Hubbard model by adopting the large-scale dynamical clus…
