纠缠熵与对偶

Entanglement Entropy and Duality

Djordje Radicevic

摘要:

利用纠缠熵的代数方法,我们研究了几个对偶对格点理论,并展示了如何在每个对偶中完全保持熵。我们的主要结果是,在一个区域中的观测量的极大代数通常对偶的非极大代数的对偶区域。特别是,我们展示了如何通常的概念,跟踪外部自由度对偶跟踪耦合到一个额外的总和superselection部门。我们简要地评论我们的结果可能扩展到更复杂的对偶,包括全息的。

英文摘要:

Using the algebraic approach to entanglement entropy, we study several dual pairs of lattice theories and show how the entropy is completely preserved across each duality. Our main result is that a maximal algebra of observables in a region typically dualizes to a non-maximal algebra in a dual region. In particular, we show how the usual notion of tracing out external degrees of freedom dualizes to a tracing out coupled to an additional summation over superselection sectors. We briefly comment on possible extensions of our results to more intricate dualities, including holographic ones.
