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,…
Instability of a Kerr black hole in f(R) gravity
Yun Soo Myung
We study the stability of a rotating (Kerr) black hole in the viable gravity. The linearized-Ricci scalar equation shows the superradiant instability, leading to the instabi…
Instability of Schwarzschild-AdS black hole in Einstein-Weyl gravity
Yun Soo Myung
We investigate the classical stability of Schwarzschild-AdS black hole in a massive theory of the Einstein-Weyl gravity. It turns out that the linearized Einstein tensor perturbati…
Comment on Ricci dark energy in Chern-Simons modified gravity
Yun Soo Myung
We revisit Ricci dark energy in Chern-Simons modified gravity. As far as the cosmological evolution, this is nothing but the Ricci dark energy with a minimally coupled scalar witho…
Late-time acceleration in the coupled Cubic Galileon models
Kyoung Yee Kim, Hyung Won Lee, Yun Soo Myung
We investigate the linearly and quadratically coupled cubic Galileon models that include linear potentials. These models may explain the late-time acceleration. In these cases, we…
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…
Stability of the massive graviton around a BTZ black hole in three dimensions
Taeyoon Moon, Yun Soo Myung
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…
