Abstract: We study the entanglement entropy of a free massive scalar field at its ground state in (3+1)-dimensional AdS space in global coordinates. We consider spherical entangling surfaces centered at the origin of AdS. We determine the structure of the UV-divergent terms in the entanglement entropy and compute the numerical values of the respective coefficients. We confirm the connection between the coefficient of the logarithmic term and the conformal anomaly.

Analytic continuations of holographic entanglement entropy in which the boundary subregion extends along a timelike direction have brought a promise of a novel, time-centric probe of spacetime.<n>We propose that the bulk carriers of this holographic timelike entanglement entropy are boundary-anchored extremal surfaces probing analytic continuation of holographic spacetimes into complex coordinates.

A Numerical Calculation of Entanglement Entropy in de Sitter Space [0.0]
entanglement entropy of a massless scalar field in de Sitter space depends on multiple scales. We derive the leading de Sitter corrections to the flat-space entanglement entropy for subhorizon entangling radii. We show that the contribution to the entanglement entropy of the sector of the theory with vanishing angular momentum depends logarithmically on the size of the overall system.

Universal terms of the entanglement entropy in a static closed universe [0.0]
We determine two universal coefficients of the entanglement entropy for a massive scalar field in a static closed universe. The first coefficient describes a well known generic correction to the area law independent of the geometry of the entangling surface and background. The second coefficient describes a curvature-dependent universal term with a nontrivial dependence on the intrinsic and extrinsic geometries of the entangling surface and curvature of the background.
