Instability of Small Lovelock Black Holes in Even-dimensions
Tomohiro Takahashi, Jiro Soda
We study the stability of static black holes in Lovelock theory which is a natural higher dimensional generalization of Einstein theory. We derive a master equation for tensor pert…
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…
Spin-polarized electronic structures and transport properties of Fe-Co alloys
Yohei Kota, Tomohiro Takahashi, Hiroki Tsuchiura +1
The electrical resistivities of Fe-Co alloys owing to random alloy disorder are calculated using the Kubo-Greenwood formula. The obtained electrical esistivities agree well with ex…
Stability of Lovelock Black Holes under Tensor Perturbations
Tomohiro Takahashi, Jiro Soda
We study the stability of static black holes in the third order Lovelock theory. We derive a master equation for tensor perturbations. Using the master equation, we analyze the sta…
