Dual Instability of Superconductivity from Oxygen Defects in ${\mathrm{La}}_{3}{\mathrm{Ni}}_{2}{\mathrm{O}}_{7+δ}$

Author(s): Peiheng Jiang, Jie Li, Yu-Han Cao, Xiaodong Cao, Zhicheng Zhong, Yi Lu, and Qiang-Hua Wang Oxygen defects suppress superconductivity in the bilayer nickelate La3Ni2O7+δ via a dual mechanism, revealed through density functional theory, dynamical mean-field theory, and functional renormalization group analysis.
