Some Calculable Contributions to Entanglement Entropy | | Mark P. Hertzberg
; Frank Wilczek
; | | Date: |
6 Jul 2010 | | 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. | | Source: | arXiv, 1007.0993 | | Services: | Forum | Review | PDF | Favorites | |
