Thermodynamic and classical instability of AdS black holes in fourth-order gravity
Yun Soo Myung, Taeyoon Moon
We study thermodynamic and classical instability of AdS black holes in fourth-order gravity. These include the BTZ black hole in new massive gravity, Schwarzschild-AdS black hole,…

Taeyoon Moon, Yun Soo Myung
We find the Gregory-Laflamme -mode instability of the non-rotating BTZ black hole in new massive gravity. This instability shows that the BTZ black hole could not exist as a sta…
Quantization of n coupled scalar field theory
Yong-Wan Kim, Yun Soo Myung, Young-Jai Park
We study a model of n coupled scalar fields in Minkowski spacetime where all masses degenerate, which is considered as a toy model of polycritical gravity on AdS spacetime. We quan…
Quasinormal frequencies of a massless scalar in the hidden Kerr/CFT proposal
Taeyoon Moon, Yun Soo Myung
The hidden Kerr/CFT proposal implies that the massless scalar wave equation in the near-region and low-frequency limit respects a hidden SL(2,R)SL(2,R) invariance in the Ke…

We investigate the massive graviton stability of the BTZ black hole obtained from three dimensional massive gravities which are classified into the parity-even and parity-odd gravi…
Modified Brans-Dicke theory with space-time anisotropic parameters
Taeyoon Moon, Phillial Oh
We consider the ADM formalism of the Brans-Dicke theory and propose an anisotropic extension of the theory by introducing five free parameters. We find that the resulting theory re…
A massive graviton in topologically new massive gravity
Yong-Wan Kim, Yun Soo Myung, Young-Jai Park
We investigate the topologically new massive gravity in three dimensions. It turns out that a single massive mode is propagating in the flat spacetime, comparing to the conformal C…

Yong-Wan Kim, Yun Soo Myung, Young-Jai Park
We show that the hidden conformal symmetry of the Schwarzschild black hole is realized from the AdS sector of the AdS, but not from the Rindler spacetime which is…

We construct a rank-3 finite temperature logarithmic conformal field theory (LCFT) starting from a higher-derivative scalar field model in the BTZ black hole background. Its zero t…
