Emergence of Gravity and RG Flow
Ayan Mukhopadhyay
- Vol. 187, pp 283-302
TLDR
In this paper, Padmanabhan et al. reformulated Einstein's equations in AdS as a non-perturbative RG flow that further leads to a new approach towards constructing strongly interacting QFTs.Abstract:
This is a tribute to Padmanabhan’s works on the holographic principle which have consistently enunciated the profound philosophy that the classical equations of gravity themselves hold the key to understanding their holographic origin. I discuss how this can be realised by reformulating Einstein’s equations in AdS as a non-perturbative RG flow that further leads to a new approach towards constructing strongly interacting QFTs. For a concrete demonstration, I focus on the hydrodynamic limit in which case this RG flow connects the AdS/CFT correspondence with the membrane paradigm.read more

A Practical Mini-Course on Applied Holography
TL;DR: In this paper, the authors present a collection of notes based on lectures given at IIT Madras in September 2019 and at IFT Madrid in November 2019 on applied holography and especially the analytic and numerical techniques involved.

Holographic gravity and the surface term in the Einstein-Hilbert action
TL;DR: In this article, it is shown that the true degrees of freedom of gravity reside in the surface term of the action, making gravity intrinsically holographic, and the bulk term can be derived from the surface terms.

Coupling hydrodynamics to nonequilibrium degrees of freedom in strongly interacting quark-gluon plasma.
TL;DR: New evolution equations for general flows are formulated and tested which reproduce the results of MIS theory when initialized close to the hydrodynamic stage of evolution, but give a more accurate description of the dynamics when initial conditions are set in the preequilibrium regime.

The Holographic Principle
TL;DR: In this paper, a pedagogical overview of the present status of high-energy physics at the Planck scale is given, and an introduction is given to a notion that became known as ''the holographic principle'' in Planck-scale physics, which is arrived at by studying quantum mechanical features of black holes.

The Holography of Gravity encoded in a relation between Entropy, Horizon area and Action for gravity
TL;DR: In this paper, a general proof of the conjecture that one can attribute an entropy to the area of any horizon is given, by constructing a canonical ensemble of a subclass of spacetimes with a fixed value for the temperature.

Diffeomorphisms, anomalies and the Fefferman-Graham ambiguity
Adam Schwimmer,Stefan Theisen +1 more
TL;DR: Using the Weyl transfomations induced by diffeomorphisms, the authors set up a cohomological problem for the Fefferman-Graham coefficients, which removed the ambiguity and gave the non-local terms in the effective action responsible for trace anomalies.
