论文摘要
根据新开发的晶格 - 孔子对应关系，本文重新审视了自由田格纠缠熵的标准计算。这种对应关系规定了一种明确的方法，可以从完全正则化的晶格理论中提取近似连续的量子场理论。该处方将在这里扩展到子区域代数，并将显示如何通过纯粹与晶格数量合作来计算连续体玻色和费米昂理论的熵。这清楚地表明了纠缠熵中差异的起源，同时还提出了一个简洁而详细的配方，用于计算连续理论中的这一重要数量。
This paper revisits standard calculations of free field entanglement entropy in light of the newly developed lattice-continuum correspondence. This correspondence prescribes an explicit method to extract an approximately continuum quantum field theory out of a fully regularized lattice theory. This prescription will here be extended to subregion algebras, and it will be shown how entropies of continuum boson and fermion theories can be computed by working purely with lattice quantities. This gives a clear picture of the origin of divergences in entanglement entropy while also presenting a concise and detailed recipe for calculating this important quantity in continuum theories.
