Cosmological particle production at strong coupling (2015)
Journal Article
Rangamani, M., Rozali, M., & Van Raamsdonk, M. (2015). Cosmological particle production at strong coupling. Journal of High Energy Physics, 2015(9), Article 213. https://doi.org/10.1007/jhep09%282015%29213

We study the dynamics of a strongly-coupled quantum field theory in a cosmological spacetime using the holographic AdS/CFT correspondence. Specifically we consider a confining gauge theory in an expanding FRWuniverse and track the evolution of the st... Read More about Cosmological particle production at strong coupling.

Spatial modulation and conductivities in effective holographic theories (2015)
Journal Article
Rangamani, M., Rozali, M., & Smyth, D. (2015). Spatial modulation and conductivities in effective holographic theories. Journal of High Energy Physics, 2015(7), Article 24. https://doi.org/10.1007/jhep07%282015%29024

We analyze a class of bottom-up holographic models for low energy thermo-electric transport. The models we focus on belong to a family of Einstein-Maxwell-dilaton theories parameterized by two scalar functions, characterizing the dilaton self-interac...

Adiabatic hydrodynamics: the eightfold way to dissipation (2015)
Journal Article
Haehl, F. M., Loganayagam, R., & Rangamani, M. (2015). Adiabatic hydrodynamics: the eightfold way to dissipation. Journal of High Energy Physics, 2015(5), Article 60. https://doi.org/10.1007/jhep05%282015%29060

Hydrodynamics is the low-energy effective field theory of any interacting quantum theory, capturing the long-wavelength fluctuations of an equilibrium Gibbs densitymatrix. Conventionally, one views the effective dynamics in terms of the conserved cur... Read More about Adiabatic hydrodynamics: the eightfold way to dissipation.

Permutation orbifolds and holography (2015)
Journal Article
Haehl, F., & Rangamani, M. (2015). Permutation orbifolds and holography. Journal of High Energy Physics, 2015(3), Article 163. https://doi.org/10.1007/jhep03%282015%29163

Two dimensional conformal field theories with large central charge and a sparse low-lying spectrum are expected to admit a classical string holographic dual. We construct a large class of such theories employing permutation orbifold technology. In pa... Read More about Permutation orbifolds and holography.

Hydrodynamic Regimes of Spinning Black D3-Branes (2015)
Journal Article
Erdmenger, J., Rangamani, M., Steinfurt, S., & Zeller, H. (2015). Hydrodynamic Regimes of Spinning Black D3-Branes. Journal of High Energy Physics, 2015(2), Article 026. https://doi.org/10.1007/jhep02%282015%29026

We present the long-wavelength effective description of non-extremal spinning black D3-branes in flat space. Our setup is motivated by recent explorations of low energy dynamics on black brane world-volumes within the blackfold approach and its conne...

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

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.
