A Note on Separability of Field Equations in Myers-Perry Spacetimes
Keiju Murata, Jiro Soda
We study separability of scalar, vector and tensor fields in 5-dimensional Myers-Perry spacetimes with equal angular momenta. In these spacetimes, there exists enlarged symmetry, $…
Kaluza-Klein braneworld cosmology with static internal dimensions
Sugumi Kanno, David Langlois, Misao Sasaki +1
We investigate the Kaluza-Klein braneworld cosmology from the point of view of observers on the brane. We first generalize the Shiromizu-Maeda-Sasaki (SMS) equations to higher dime…
Circular Polarization of Primordial Gravitational Waves in String-inspired Inflationary Cosmology
Masaki Satoh, Sugumi Kanno, Jiro Soda
We study a mechanism to produce the circular polarization of primordial gravitational waves. The circular polarization is generated during the super-inflation driven by the Gauss-B…
Fate of Kaluza-Klein Black Holes: Evaporation or Excision?
Keiju Murata, Jiro Soda, Sugumi Kanno
We study evaporation process of black strings which are typical examples of Kaluza-Klein black holes. Taking into account the backreaction of the Hawking radiation, we deduce the e…
Hawking Radiation from Squashed Kaluza-Klein Black Holes -- A Window to Extra Dimensions --
Hideki Ishihara, Jiro Soda
We explore the obsevability of extra dimensions through 5-dimensional squashed Kaluza-Klein black holes residing in the Kaluza-Klein spacetime. With the expectation that the Hawkin…
Evaporating (2+1)-dimensional black strings
Keiju Murata, Jiro Soda, Sugumi Kanno
We investigate (2+1)-dimensional black strings in the Kaluza-Klein spacetime. The system is classically stable as long as the horizon size is much larger than the size of the compa…
