Gravity is an attractive force that affects and is affected by all mass and - in general relativity - energy, pressure, and stress. Prefer newtonian-gravity or general-relativity if sensible.

The energy of dual boundary field in AdS/CFT
In AdS/CFT, when the spacetime is a planar AdS black hole with dimension ($d+1$), the corresponding energy of boundary field theory is proportional to the black hole mass parameter. For example when $ …

Temperature in CFT
Non-vanishing Temperature can break conformal symmetry (Can anyone show this point explicitly), my question is that in AdS/CFT the temperature of boundary field theory is non-zero, why the boundary f …

About topological massive gravity
I am reading papers about topological massive gravity (TMG) in 3-dimensional spacetime. I come across two kinds of formalism to describe TMG. …

The black hole horizon of Jackiw-Teitelboim (JT) gravity
I am reading the papers about black hole in $AdS_2$, which can be regarded as a solution in JT gravity. … In conformal gauge the solution of JT gravity is, for metric
\begin{equation}
ds^2=-e^{2w(x^+,x^-)}dx^+dx^-=-\frac{4}{(x^+-x^-)^2}dx^+dx^-
\end{equation}
and for dilaton
\begin{equation}
\phi=\frac{a+b …

holography dual in flat spacetime
In AdS/CFT the bulk geometry is AdS spacetime, the flat limit of AdS is taking to the radius of AdS to infinity. By taking this limit can one get the holography dual in flat spacetime from AdS/CFT, or …
