Entanglement entropy of subtracted geometry black holes
We compute the entanglement entropy of minimally coupled scalar fields on
subtracted geometry black hole backgrounds, focusing on the logarithmic
corrections. We notice that matching between the entanglement entropy of
original black holes and their subtracted counterparts is only at the order of
the area term. The logarithmic correction term is not only different but also,
in general, changes sign in the subtracted case. We apply Harrison
transformations to the original black holes and find out the choice of the
Harrison parameters for which the logarithmic corrections vanish.Comment: 15 page
