Chiral Primordial Gravitational Waves from a Lifshitz Point
Tomohiro Takahashi, Jiro Soda
We study primordial gravitational waves produced during inflation in quantum gravity at a Lifshitz point proposed by Hoava. Assuming power-counting renormalizabilit…
Inflationary Universe with Anisotropic Hair
Masa-aki Watanabe, Sugumi Kanno, Jiro Soda
We study an inflationary scenario with a vector field coupled with an inflaton field and show that the inflationary universe is endowed with anisotropy for a wide range of coupling…
Evolution of perturbations of squashed Kaluza-Klein black holes: escape from instability
Hideki Ishihara, Masashi Kimura, Roman A. Konoplya +3
The squashed Kaluza-Klien (KK) black holes differ from the Schwarzschild black holes with asymptotic flatness or the black strings even at energies for which the KK modes are not e…
Stability of Five-dimensional Myers-Perry Black Holes with Equal Angular Momenta
Keiju Murata, Jiro Soda
We study the stability of five-dimensional Myers-Perry black holes with equal angular momenta which have an enlarged symmetry, U(2). Using this symmetry, we derive master equations…
Hawking Radiation from Rotating Black Holes and Gravitational Anomalies
Keiju Murata, Jiro Soda
We study the Hawking radiation from Rotating black holes from gravitational anomalies point of view. First, we show that the scalar field theory near the Kerr black hole horizon ca…
Radionic Non-uniform Stable Black Strings
Takashi Tamaki, Sugumi Kanno, Jiro Soda
Non-uniform black strings in the two-brane system are investigated using the effective action approach. It is shown that the radion acts as a non-trivial hair of black strings. The…
