We identify various universal contributions to the entanglement entropy for massive free fields. As well as the 'area' terms found in , we find other geometric contributions of the form discussed in . We also compute analogous contributions for a strongly coupled field theory using the AdS/CFT correspondence. In this case, we find the results for strong and weak coupling do not agree.
