Gregory-Laflamme instability of BTZ black hole in new massive gravity
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…
Unstable Schwarzschild-Tangherlini black holes in fourth-order gravity
Yun Soo Myung
We study the stability of Schwarzschild-Tangherlini (ST) black holes in fourth-order gravity which provides a higher dimensional linearized massive equation. The linearized-Ricci t…
Stability of Schwarzschild black holes in fourth-order gravity revisited
Yun Soo Myung
We revisit the classical stability of Schwarzschild black hole in fourth-order theories of gravity. On the contrary of the stability of this black hole, it turns out that the linea…
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…
BRST quantization of a sixth-order derivative scalar field theory
Yong-Wan Kim, Yun Soo Myung, Young-Jai Park
We study a sixth order derivative scalar field model in Minkowski spacetime as a toy model of higher-derivative critical gravity theories. This model is consistently quantized when…
