在平坦空间中,我们考虑了跨越平面边界的纠缠。纠缠熵通常被认为是约化密度矩阵的冯诺依曼熵,但它也可以被认为是约化密度矩阵的乘积的一半。后一种形式允许一个自然的调节器,其中两个圆锥体被平滑成欧几里得沙漏几何形状。由于不需要对希尔伯特空间进行张量因子化,调节熵显然是规范不变的,并且具有明显的状态计数解释。我们探讨这个处方标量场,熵是不敏感的非最小耦合,和麦克斯韦场,它有相同的熵作为标量。
We consider entanglement across a planar boundary in flat space. Entanglement entropy is usually thought of as the von Neumann entropy of a reduced density matrix, but it can also be thought of as half the von Neumann entropy of a product of reduced density matrices on the left and right. The latter form allows a natural regulator in which two cones are smoothed into a Euclidean hourglass geometry. Since there is no need to tensor factor the Hilbert space, the regulated entropy is manifestly gauge invariant and has a manifest state-counting interpretation. We explore this prescription for scalar fields, where the entropy is insensitive to a nonminimal coupling, and for Maxwell fields, which have the same entropy asscalars.
