Confining potential in holographic bottom-up QCD from WKB
Miguel Angel Martin Contreras, Mitsutoshi Fujita, Alfredo Vega
By using the \emph{Rydberg--Klein--Rees} (RKR) formulas to solve the inverse Schrödinger problem, we found a confining bottom-up potential from a given eigenvalue spectrum. To ill…

Geometric entropy and time-like entanglement entropy on a rotating BTZ black hole
Huayu Dai, Xi-Hao Fang, Mitsutoshi Fujita +1
In this paper, we analyze the double Wick rotation of a rotating BTZ black hole and the entanglement entropy. We derive the transition matrix dual to the double Wick-rotated BTZ bl…

Notes on the double Wick rotated BTZ black hole
Hua-Yu Dai, Xi-Hao Fang, Mitsutoshi Fujita
We analyze the double Wick rotated BTZ black hole with the Euclidean signature, which is a Riemannian manifold. We calculate thermodynamics, total energy of spacetime, and holograp…
