Is there any proposed holographic/thermodynamic interpretation of gravitational time dilation?
In AdS/CFT and holography more generally, many proposals of various degrees of plausibility have been made linking apparently physical notions on the bulk side to more information-theoretic, ...

Do all small-large AdS black hole phase transitions have swallow tail like behaviour for the Free Energy v/s Temperature plot?
In the literature the swallow tail like behaviour is prominently seen for small-large AdS black hole phase transition for the Free Energy vs Temperature Plot. Recently I was trying to reproduce the ...

Measuring "complexity"
A recently popular idea in the quantum theory of black holes is that there is an isomorphism between the interior state's volume and the computational complexity of the CFT dual (in an AdS/CFT setting)...

Definitions of Thermodynamics and Holography
There are many differences between the laws of thermodynamics and the laws of black hole thermodynamics (BHT):
Zeroth Law: In thermodynamics, the Zeroth Law establishes the notion of thermal ...

Relating phase transition with symmetry-breaking according to Landau Theory
I am trying to reproduce the results from this paper where they find out the expression for the Landau functional to be
$$\psi(x,t,p)=\frac{1}{4}(\frac{1}{x}+6x+px^3-4tx^2)$$
Now we plot Landau ...

Hawking Temperature for a hairy BTZ Black Hole
The metric of a hairy Black Hole is given by:
$$ds^2 = \frac{L^2}{z^2}\biggl(-g(z) dt^2 + \frac{e^{2 A(z)}}{g(z)} dz^2 +d\varphi^2\biggr), $$
where $L$ is the AdS length taken to be $1$,$A(z)$ is the ...

Temperature of AdS-Schwarzchild black holes? How physics is the same for different temperatures?
The five dimensional Schwarzchild-AdS black brane's metric is given by
$$
ds^2_5=-\left(\frac{r}{L}\right)^2h(r)dt^2+\frac{dr^2}{\left(\frac{r}{L}\right)^2h(r)}+\left(\frac{r}{L}\right)^2(dx^2+dy^2+dz^...

Describing spacetime with qubits
Susskind in one of his lectures at PiTP 2018 on Complexity and Gravity talks about describing black holes as a qubit system, comprising qubits of the order of the entropy of the black hole. This is ...

Never underestimate thermodynamics (especially when it relates to gravity)
In the review paper by Subir Sachdev, the low-temperature effective action of charged SYK models has been derived using holography.
In section 4, arguments of thermodynamics are used to derive the ...

Hawking-Page Phase Transition for Charged AdS Black Holes
My question is concerned with the vacuum state of charged black holes in a Hawking-Page type phase transition.
Is the vacuum of a charged AdS$_d$ black hole a pure AdS$_d$ spacetime or an AdS$_d$ ...

How can a non-expert think of Black Hole microstates?
For someone familiar with basic QFT and GR and semi-classical physics but doesn't know string theory nor AdS/CFT is there some intuitive way to think about what the microstate of a black hole means?

On the Schwarzchild black hole metric:
I've been going through the introduction on Ads/CFT by Horatiu Nastase (https://arxiv.org/abs/0712.0689). In chapter 5, "Black holes and p branes", in Eq. 5.2, it is mentioned the schwarzchild metric ...

Is Wilson loop particle heavier than black hole in AdS-CFT at finite temp?
Finite temperature is introduced in the Ads Space by inserting a black hole. In the Ads-CFT correspondence, the Wilson loop is at $u \rightarrow \infty$. But the black hole horizon itself would be at $...

Naked singularity and AdS/CFT
I am a bit confused about the status of naked singularities that appear in black hole physics and more so in the context of AdS/CFT. Here is what I know about this in brief.
For a charged Reissner-...

Why does AdS/CFT with non-zero temperature correspond to a black hole in the bulk?
Is there a good intuitive explanation on why AdS/CFT with non-zero temperature corresponds to a black hole in the bulk? And what is the role of temperature and chemical potential in this black hole?
