Vanishing Love of Black Holes in General Relativity: From Spacetime Conformal Symmetry of a Two-dimensional Reduced Geometry
Takuya Katagiri, Masashi Kimura, Hiroyuki Nakano +1
We study the underlying structure of the vanishing of the Love numbers of both Schwarzschild and Kerr black holes in terms of spacetime conformal symmetry in a unified manner for t…

Ladder operators and quasinormal modes in Bañados-Teitelboim-Zanelli black holes
Takuya Katagiri, Masashi Kimura
We study quasinormal modes (QNMs) of massive Klein-Gordon fields in static Bañados-Teitelboim-Zanelli (BTZ) black holes in terms of ladder operators constructed from spacetime conf…
