The topologically twisted index for ABJM theory with gauge group U(

has recently been shown, in the large-
N
limit, to reproduce the BekensteinHawking entropy of certain magnetically charged asymptotically AdS

black holes. We numerically study the index beyond the large-
N
limit and provide evidence that it contains a subleading logarithmic term of the form −1

. On the holographic side, this term naturally arises from a one-loop computation. However, we find that the contribution coming from the near horizon states does not reproduce the field theory answer. We give some possible reasons for this apparent discrepancy. |
