Title: Some Calculable Contributions to Entanglement Entropy
Title: 一些可计算的纠缠熵贡献
Abstract: By considering parametric dependence on mass, we extract finite, calculable contributions to the entanglement entropy for a massive scalar field between the interior and exterior of a spatial domain of arbitrary shape. The leading term is proportional to the area of the dividing boundary; we also extract finite subleading contributions for a field defined in the bulk interior of a waveguide in 3+1 dimensions, including terms proportional to the waveguide's cross-sectional geometry; its area, perimeter length, and integrated curvature. We also consider related quantities for massless fields and suggest a class of systems for which these contributions might be measurable.
