Abstract

The supersymmetric R\'enyi entropy across a spherical entangling surface in a dd-dimensional SCFT with flavor defects is equivalent to a supersymmetric partition function on Hd1×S1\mathbb{H}^{d-1} \times \mathbb{S}^1, which can be computed exactly using localization. We consider the holographically dual BPS solutions in (d+1)(d +1)-dimensional matter coupled supergravity (d=3,5)(d = 3 , 5), which are charged hyperbolically sliced AdS black holes. We compute the renormalized on-shell action and the holographic supersymmetric R\'enyi entropy and show a perfect match with the field theory side. Our setup allows a direct map between the chemical potentials for the global symmetries of the field theories and those of the gravity solutions. We also discuss a simple case where angular momentum is added.
