3+1维平板几何Maxwell场的纠缠熵

On Entanglement Entropy of Maxwell fields in 3+1 dimensions with a slab geometry

Candost Akkaya, Alex Kovner

摘要:

在纯Maxwell理论中计算了有限宽平板的纠缠熵。我们发现,熵的很大一部分是由一个模式的纠缠,非本地的横向磁场自由度。即使纠缠模式是非局部的,它对熵的贡献是局部的,在这个意义上,有限厚度的板的熵等于边界的熵加上板厚度的校正指数。

英文摘要:

We calculate the entanglement entropy of a slab of finite width in the pure Maxwell theory. We find that a large part of entropy is contributed by the entanglement of a mode, nonlocal in terms of the transverse magnetic field degrees of freedom. Even though the entangled mode is nonlocal, its contribution to the entropy is local in the sense that the entropy of a slab of a finite thickness is equal to the entropy of the boundary plus a correction exponential in thickness of the slab.
