A bstractWe compute entanglement entropy for free massive scalar fields in anti-de Sitter (AdS) space. The entangling surface is a minimal surface whose boundary is a sphere at the boundary of AdS. The entropy can be evaluated from the thermal free energy of the fields on a topological black hole by using the replica method. In odd-dimensional AdS, exact expressions of the Rényi entropy Sn are obtained for arbitrary n. We also evaluate 1-loop corrections coming from the scalar fields to…

Target space entanglement in quantum mechanics of fermions and matrices
TLDR
It is shown that the upper bounds of the general Rényi entropies are N log 2 for N particles or an N × N matrix, and the target space entanglement entropy and the mutual information in a free one-matrix model are computed.
Effects of non-conformal boundary on entanglement entropy
Spacetime boundaries with canonical Neuman or Dirichlet conditions preserve conformal invarience, but "mixed" boundary conditions which interpolate linearly between them can break conformal symmetry

It is argued that the entanglement entropy in d + 1 dimensional conformal field theories can be obtained from the area of d dimensional minimal surfaces in AdS(d+2), analogous to the Bekenstein-Hawking formula for black hole entropy.
