Comments on Hall transport from effective actions (2013)
Journal Article
Haehl, F. M., & Rangamani, M. (2013). Comments on Hall transport from effective actions. Journal of High Energy Physics, 2013(10), https://doi.org/10.1007/jhep10%282013%29074

We consider parity-odd transport in 2+1 dimensional charged fluids restricting attention to the class of non-dissipative fluids. We show that there is a two parameter family of such non-dissipative fluids which can be derived from an effective action... Read More about Comments on Hall transport from effective actions.

Global properties of causal wedges in asymptotically AdS spacetimes (2013)
Journal Article
Hubeny, V. E., Rangamani, M., & Tonni, E. (2013). Global properties of causal wedges in asymptotically AdS spacetimes. Journal of High Energy Physics, 2013(10), https://doi.org/10.1007/jhep10%282013%29059

We examine general features of causal wedges in asymptotically AdS space-times and show that in a wide variety of cases they have non-trivial topology. We also prove some general results regarding minimal area surfaces on the causal wedge boundary an... Read More about Global properties of causal wedges in asymptotically AdS spacetimes.

Holographic entanglement plateaux (2013)
Journal Article
Hubeny, V. E., Maxfield, H., Rangamani, M., & Tonni, E. (2013). Holographic entanglement plateaux. Journal of High Energy Physics, 2013(8), https://doi.org/10.1007/jhep08%282013%29092

We consider the entanglement entropy for holographic field theories in finite volume. We show that the Araki-Lieb inequality is saturated for large enough subregions, implying that the thermal entropy can be recovered from the knowledge of the region...

Effective hydrodynamics of black D3-branes (2013)
Journal Article
Emparan, R., Hubeny, V. E., & Rangamani, M. (2013). Effective hydrodynamics of black D3-branes. Journal of High Energy Physics, 2013(6), Article 2013:35. https://doi.org/10.1007/jhep06%282013%29035

The long-wavelength effective field theory of world-volume fluctuations of black D3-branes is shown to be a hydrodynamical system to leading order in a gradient expansion. We study the system on a fiducial ‘cutoff’ surface: the fluctuating geometry i... Read More about Effective hydrodynamics of black D3-branes.

Thermalization of causal holographic information (2013)
Journal Article
Hubeny, V. E., Rangamani, M., & Tonni, E. (2013). Thermalization of causal holographic information. Journal of High Energy Physics, 2013(5), Article 136. https://doi.org/10.1007/jhep05%282013%29136

We study causal wedges associated with a given sub-region in the boundary of asymptotically AdS spacetimes. Part of our motivation is to better understand the recently proposed holographic observable, causal holographic information, χ, which is given...

Non-dissipative hydrodynamics: Effective actions versus entropy current (2013)
Journal Article
Bhattacharya, J., Bhattacharyya, S., & Rangamani, M. (2013). Non-dissipative hydrodynamics: Effective actions versus entropy current. Journal of High Energy Physics, 2013(2), Article 153. https://doi.org/10.1007/jhep02%282013%29153

While conventional hydrodynamics incorporating dissipative effects is hard to derive from an action principle, it is nevertheless possible to construct classical actions when the dissipative terms are switched off. In this note we undertake a systema... Read More about Non-dissipative hydrodynamics: Effective actions versus entropy current.
