Traversability of Multi-Boundary Wormholes
Abdulrahim Al Balushi, Zhencheng Wang, Donald Marolf
We generalize the Gao-Jafferis-Wall construction of traversable two-sided wormholes to multi-boundary wormholes. In our construction, we take the background spacetime to be multi-b…
Holographic Complexity and Thermodynamic Volume
Abdulrahim Al Balushi, Robie A. Hennigar, Hari K. Kunduri +1
We study the holographic complexity conjectures for rotating black holes, uncovering a relationship between the complexity of formation and the thermodynamic volume of the black ho…
Null Hypersurfaces in Kerr-Newman-AdS Black Hole and Super-Entropic Black Hole Spacetimes
Michael T. N. Imseis, Abdulrahim Al Balushi, Robert B. Mann
A three-dimensional light-like foliation of a spacetime geometry is one particular way of studying its light cone structure and has important applications in numerical relativity.…
Null hypersurfaces in Kerr-(A)dS spacetimes
Abdulrahim Al Balushi, Robert B. Mann
For many purposes, a three-dimensional foliation of spacetime is more advantageous to understanding its light cone structure. We derive the equations describing such foliations for…
