Quasinormal Modes of pp-Wave Spacetimes and Zero Temperature Dissipation
Huayu Dai, Guangtao Zeng
We compute the quasinormal mode spectrum of scalar perturbations on Kaigorodov pp-wave spacetimes, the horizonless gravity duals of zero temperature null fluids. The pp-wave deform…
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…
On the emergence of gravitational dynamics from tensor networks
Jia-Rui Sun, Yuan Sun
Tensor networks are powerful techniques that widely used in condensed matter physics. In this language, the wave function of a quantum manybody system is described by a network of…
