Observations on entanglement entropy in massive QFT's

Lewkowycz, Aitor, Myers, Robert C., Smolkin, Michael

Understand

We identify various universal contributions to the entanglement entropy for massive free fields.

As well as the `area' terms found in [1], we find other geometric contributions of the form discussed in [2].
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.
