| 英文摘要 | A sort of planar tensor network with tensor constraints is investigated as a model for holography. We study the greedy algorithm generated by tensor constraints and propose the notion of critical protection (CP) against the action of greedy algorithm. For given tensor constraints, a CP tensor chain can be defined. We further find that the ability of quantum error correction (QEC), the non-flatness of entanglement spectrum (ES) and the correlation function can be quantitatively evaluated by the geometric structure of CP tensor chain. Four classes of tensor networks with different properties of entanglement are discussed. Thanks to tensor constraints and CP, the correlation function is reduced into a bracket of matrix production state and the result agrees with the one in conformal field theory. |
