Causally pathological space-times are physically relevant (2005)
Journal Article
Hubeny, V. E., Rangamani, M., & Ross, S. F. (2005). Causally pathological space-times are physically relevant. International Journal of Modern Physics D, 14(12), 2227-2232. https://doi.org/10.1142/s0218271805007760

We argue that in the context of string theory, the usual restriction to globally hyperbolic space–times should be considerably relaxed. We exhibit an example of a space–time which only satisfies the causal condition, and so is arbitrarily close to ad... Read More about Causally pathological space-times are physically relevant.

Causal structures and holography (2005)
Journal Article
Hubeny, V. E., Rangamani, M., & Ross, S. F. (2005). Causal structures and holography. Journal of High Energy Physics, 2005(07), Article 037. https://doi.org/10.1088/1126-6708/2005/07/037

We explore the description of bulk causal structure in a dual field theory. We observe that in the spacetime dual to a spacelike non-commutative field theory, the causal structure in the boundary directions is modified asymptotically. We propose that...

Nonsupersymmetric smooth geometries and D1-D5-P bound states (2005)
Journal Article
Jejjala, V., Madden, O., Ross, S., & Titchener, G. (2005). Nonsupersymmetric smooth geometries and D1-D5-P bound states. Physical Review D, Particles and fields, 71(12), https://doi.org/10.1103/physrevd.71.124030

We construct smooth nonsupersymmetric soliton solutions with D1-brane, D5-brane, and momentum charges in type IIB supergravity compactified on T4×S1, with the charges along the compact directions. This generalizes previous studies of smooth supersymm... Read More about Nonsupersymmetric smooth geometries and D1-D5-P bound states.
