报告摘要:
Partial entanglement entropy (PEE) characterizes how much the subsets of A contribute to the entanglement entropy S_A. We find one additional physical requirement for PEE, which is the invariance under a permutation between the subset and the complementary region of A. Together with the other known requirements we find that, in quantum field theories with Poincare symmetry PEE should satisfy a general formula thus can be uniquely defined. Based on this formula we can in general write PEE as a linear combination of subset entanglement entropies for a generic partition.
