Holographic dual of collimated radiation (2011)
Journal Article
Hubeny, V. (2011). Holographic dual of collimated radiation. New Journal of Physics, 13(3), Article 035006. https://doi.org/10.1088/1367-2630/13/3/035006

We propose a new and simple method of estimating the radiation due to an accelerated quark in a strongly coupled medium, within the framework of the anti-de Sitter (AdS)/conformal field theory (CFT) correspondence. In particular, we offer a heuristic... Read More about Holographic dual of collimated radiation.

Hawking radiation from AdS black holes (2010)
Journal Article

We study Hartle–Hawking-like states of quantum field theories on asymptotically AdS black hole backgrounds, with particular regard to the phase structure of interacting theories. By a suitable analytic continuation we show that the equilibrium dynami... Read More about Hawking radiation from AdS black holes.

Hawking radiation in large N strongly-coupled field theories (2010)
Journal Article
Hubeny, V. E., Marolf, D., & Rangamani, M. (2010). Hawking radiation in large N strongly-coupled field theories. Classical and Quantum Gravity, 27(9), Article 095015. https://doi.org/10.1088/0264-9381/27/9/095015

We consider strongly coupled field theories at large N on black hole backgrounds. At sufficiently high Hawking temperature TH, one expects a phase where the black hole is in equilibrium with a deconfined plasma. We explore this phase in the context o...

Black funnels and droplets from the AdS C-metrics (2010)
Journal Article

We recently argued that the dynamics of strongly coupled field theories in black hole backgrounds is related via the AdS/CFT correspondence to two new classes of AdS black hole solutions: black funnels and black droplets suspended above a second disc...

A Holographic view on physics out of equilibrium (2010)
Journal Article
Hubeny, V. E., & Rangamani, M. (2010). A Holographic view on physics out of equilibrium. Advances in High Energy Physics, 2010, Article 297916. https://doi.org/10.1155/2010/297916

We review the recent developments in applying holographic methods to understand nonequilibrium physics in strongly coupled field theories. The emphasis will be on elucidating the relation between evolution of quantum field theories perturbed away fro... Read More about A Holographic view on physics out of equilibrium.

Dynamical black holes and expanding plasmas (2009)
Journal Article

We analyse the global structure of time-dependent geometries dual to expanding plasmas, considering two examples: the boost invariant Bjorken flow, and the conformal soliton flow. While the geometry dual to the Bjorken flow is constructed in a pertur... Read More about Dynamical black holes and expanding plasmas.

Local Fluid Dynamical Entropy from Gravity (2008)

Spacetime geometries dual to arbitrary fluid flows in strongly coupled = 4 super Yang Mills theory have recently been constructed perturbatively in the long wavelength limit. We demonstrate that these geometries all have regular event horizons, and d... Read More about Local Fluid Dynamical Entropy from Gravity.

A covariant holographic entanglement entropy proposal (2007)

With an aim towards understanding the time-dependence of entanglement entropy in generic quantum field theories, we propose a covariant generalization of the holographic entanglement entropy proposal of hep-th/0603001. Apart from providing several ex... Read More about A covariant holographic entanglement entropy proposal.

We discuss the relation between singularities of correlation functions and causal properties of the bulk spacetime in the context of the AdS/CFT correspondence. In particular, we argue that the boundary field theory correlation functions are singular... Read More about Bulk-cone singularities & signatures of horizon formation in AdS/CFT.
