Scattering amplitudes in Lifshitz spacetime (2014)
Journal Article
Andrade, T., Ross, S. F., & Lei, Y. (2014). Scattering amplitudes in Lifshitz spacetime. Classical and Quantum Gravity, 31(21), Article 215002. https://doi.org/10.1088/0264-9381/31/21/215002

We consider the calculation of scattering amplitudes in field theories dual to Lifshitz spacetimes. These amplitudes provide an interesting probe of the IR structure of the field theory; our aim is to use them to explore the observable consequences o...

On the oscillation of species (2014)
Journal Article
Bena, I., Ross, S., & Warner, N. (2014). On the oscillation of species. Journal of High Energy Physics, 2014(9), Article 113. https://doi.org/10.1007/jhep09%282014%29113

We describe a new class of BPS objects called magnetubes: their supersymmetry is determined by their magnetic charges, while their electric charges can oscillate freely between different species. We show how to incorporate these objects into microsta... Read More about On the oscillation of species.

Multiboundary Wormholes and Holographic Entanglement (2014)
Journal Article
Balasubramanian, V., Hayden, P., Maloney, A., Marolf, D., & Ross, S. (2014). Multiboundary Wormholes and Holographic Entanglement. Classical and Quantum Gravity, 31(18), Article 185015. https://doi.org/10.1088/0264-9381/31/18/185015

The AdS/CFT correspondence relates quantum entanglement between boundary conformal field theories and geometric connections in the dual asymptotically anti-de Sitter spacetime. We consider entangled states in the $n$-fold tensor product of a 1 + 1 di... Read More about Multiboundary Wormholes and Holographic Entanglement.

Black holes, entanglement and random matrices (2014)
Journal Article
Balasubramanian, V., Berkooz, M., Ross, S. F., & Simón, J. (2014). Black holes, entanglement and random matrices. Classical and Quantum Gravity, 31(18), https://doi.org/10.1088/0264-9381/31/18/185009

We provide evidence that strong quantum entanglement between Hilbert spaces does not generically create semiclassical wormholes between the corresponding geometric regions in the context of the AdS/CFT correspondence. We propose a description of low-... Read More about Black holes, entanglement and random matrices.

Coiffured black rings (2014)
Journal Article
Bena, I., Ross, S. F., & Warner, N. P. (2014). Coiffured black rings. Classical and Quantum Gravity, 31(16), https://doi.org/10.1088/0264-9381/31/16/165015

We describe a new type of hair on supersymmetric black string and black ring solutions, which produces the largest known violation of black hole uniqueness, parameterized by an arbitrary function and hence an infinite number of continuous parameters.... Read More about Coiffured black rings.

Entanglement and correlations near extremality: CFTs dual to Reissner-Nordström AdS5 (2014)
Journal Article
Andrade, T., Fischetti, S., Marolf, D., Ross, S. F., & Rozali, M. (2014). Entanglement and correlations near extremality: CFTs dual to Reissner-Nordström AdS5. Journal of High Energy Physics, 2014(4), Article 23. https://doi.org/10.1007/jhep04%282014%29023

We use the AdS/CFT correspondence to study models of entanglement and correlations between two d = 4 CFTs in thermofield double states at finite chemical potential. Our bulk spacetimes are planar Reissner-Nordström AdS black holes. We compute both th... Read More about Entanglement and correlations near extremality: CFTs dual to Reissner-Nordström AdS5.

Extending the non-singular hyperscaling violating spacetimes (2014)
Journal Article
Lei, Y., & Ross, S. F. (2014). Extending the non-singular hyperscaling violating spacetimes. Classical and Quantum Gravity, 31(3), Article 035007. https://doi.org/10.1088/0264-9381/31/3/035007

Lifshitz and hyperscaling violating geometries, which provide a holographic description of non-relativistic field theories, generically have a singularity in the infrared region of the geometry, where tidal forces for freely falling observers diverge...
