Black Tunnels and Hammocks

Understand

We construct the holographic duals to a large $N$, strongly coupled $\mathcal{N}=4$ super Yang-Mills conformal field theory defined on a four-dimensional de Sitter-Schwarzschild background.

• There are two distinct five-dimensional bulk solutions.
• One, named the black tunnel, is static and possesses two disconnected horizons.
• The other, the black hammock, contains only one horizon in the bulk.
