Causality & Holographic Entanglement Entropy (2014)
Journal Article
Headrick, M., Hubeny, V. E., Lawrence, A., & Rangamani, M. (2014). Causality & Holographic Entanglement Entropy. Journal of High Energy Physics, 2014(12), Article 162. https://doi.org/10.1007/jhep12%282014%29162

We identify conditions for the entanglement entropy as a function of spatial region to be compatible with causality in an arbitrary relativistic quantum field theory. We then prove that the covariant holographic entanglement entropy prescription (whi... Read More about Causality & Holographic Entanglement Entropy.

Quantum Channels in Quantum Gravity (2014)
Journal Article
Rangamani, M., & Rota, M. (2014). Quantum Channels in Quantum Gravity. International Journal of Modern Physics D, 23(12), Article 1442009-1. https://doi.org/10.1142/s0218271814420097

The black hole final state proposal implements manifest unitarity in the process of black hole formation and evaporation in quantum gravity, by postulating a unique final state boundary condition at the singularity. We argue that this proposal can be... Read More about Quantum Channels in Quantum Gravity.

Comments on Entanglement Negativity in Holographic Field Theories (2014)
Journal Article
Rangamani, M., & Rota, M. (2014). Comments on Entanglement Negativity in Holographic Field Theories. Journal of High Energy Physics, 2014(10), Article 60. https://doi.org/10.1007/jhep10%282014%29060

We explore entanglement negativity, a measure of the distillable entanglement contained in a quantum state, in relativistic field theories in various dimensions. We first give a general overview of negativity and its properties and then explain a wel... Read More about Comments on Entanglement Negativity in Holographic Field Theories.

Holographic thermal field theory on curved spacetimes (2014)
Journal Article
Marolf, D., Rangamani, M., & Wiseman, T. (2014). Holographic thermal field theory on curved spacetimes. Classical and Quantum Gravity, 31(6), Article 063001. https://doi.org/10.1088/0264-9381/31/6/063001

The AdS/CFT correspondence relates certain strongly-coupled CFTs with large effective central charge ceff to semi-classical gravitational theories with AdS asymptotics. We describe recent progress in understanding gravity duals for CFTs on non-trivia... Read More about Holographic thermal field theory on curved spacetimes.

Effective actions for anomalous hydrodynamics (2014)
Journal Article
Haehl, F. M., Loganayagam, R., & Rangamani, M. (2014). Effective actions for anomalous hydrodynamics. Journal of High Energy Physics, 2014(3), Article 034. https://doi.org/10.1007/jhep03%282014%29034

We argue that an effective field theory of local fluid elements captures the constraints on hydrodynamic transport stemming from the presence of quantum anomalies in the underlying microscopic theory. Focussing on global current anomalies for an arbi... Read More about Effective actions for anomalous hydrodynamics.

Holographic entanglement and causal information in coherent states (2014)
Journal Article
Gentle, S. A., & Rangamani, M. (2014). Holographic entanglement and causal information in coherent states. Journal of High Energy Physics, 2014(1), https://doi.org/10.1007/jhep01%282014%29120

Scalar solitons in global AdS4 are holographically dual to coherent states carrying a non-trivial condensate of a scalar operator. We study the holographic information content of these states, focusing on a particular spatial region, by examining the...

The Spectrum of Light States in Large N Minimal Models (2014)
Journal Article
Gaberdiel, M., Gopakumar, R., & Rangamani, M. (2014). The Spectrum of Light States in Large N Minimal Models. Journal of High Energy Physics, 2014(1), https://doi.org/10.1007/jhep01%282014%29116

WN,k minimal models possess an interesting class of ‘light’ primaries which control much of the low energy density of states in the large N ’t Hooft limit. In this paper we conduct a detailed exploration of their distribution using a combination of n... Read More about The Spectrum of Light States in Large N Minimal Models.
