Fast scrambling as Brownian motion in a fluid with negative viscosity
Kostiantyn Ropotenko
It is shown that the fast scrambling of information in a black hole can be viewed as Brownian motion of information in a fluid with negative viscosity (and negative temperature). I…
Central charge
K. Ropotenko
Proceeding in exactly the same way as in the derivation of the temperature of a dual CFT for the extremal black hole in the Kerr/CFT correspondence, it is found that the temperatur…
Black hole motion in Euclidean space as a diffusion process II
K. Ropotenko
A diffusion equation approach to black hole thermodynamics in Euclidean sector is proposed. A diffusion equation for a generic in Euclidean sector is derived from the Bloch equatio…
Black hole motion in Euclidean space as a diffusion process
Kostiantyn Ropotenko
A diffusion equation for a black hole is derived from the Bunster-Carlip equations. Its solution has the standard form of a Gaussian distribution. The second moment of the distribu…
Rotational terms and quantum degeneracy in black holes
Kostiantyn Ropotenko
It is believed that the first law of black-hole mechanics has no independent physical significance and acquires it only after identifying with the first law of thermodynamics. It i…
The quantum of area and a statistical interpretation of black hole entropy
Kostiantyn Ropotenko
In contrast to alternative values, the quantum of area does not follow from the usual statistical interpretation of black hole entropy; on the contrary, a statisti…
