Journal Article

We describe the asymptotic boundary of the general homogeneous plane wave spacetime, using a construction of the 'points at infinity' from the causal structure of the spacetime as introduced by Geroch, Kronheimer and Penrose. We show that this constr... Read More about Plane waves: To infinity and beyond!.

The dual of nothing (2002)
Journal Article
Balasubramanian, V., & Ross, S. F. (2002). The dual of nothing. Physical Review D, Particles and fields, 66(8), https://doi.org/10.1103/physrevd.66.086002

We consider “bubbles of nothing” constructed by analytically continuing black hole solutions in anti–de Sitter space. These provide interesting examples of smooth time-dependent backgrounds which can be studied through the AdS/CFT correspondence. Our... Read More about The dual of nothing.
