Dual instability of superconductivity from oxygen defects in LaNiO
Peiheng Jiang, Jie Li, Yu-Han Cao +4
We uncover a dual mechanism by which oxygen defects suppress superconductivity in the bilayer nickelate LaNiO using density functional theory, dynamical mean-field…

Encoding computationally hard problems in triangular Rydberg atom arrays
Xi-Wei Pan, Huan-Hai Zhou, Yi-Ming Lu +1
Rydberg atom arrays are a promising platform for quantum optimization, encoding computationally hard problems by reducing them to independent set problems with unit-disk graph topo…
