Perpendicular electric field induced competing - and -wave pairings in LaNiO thin film
Yongping Wei, Xun Liu, Fan Yang +1
Inspired by the possibility that superconducting properties may be altered by applying a perpendicular electric field in the Ruddlesden-Popper (RP) bilayer nickelate LaNiO$…
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…
