Black-hole microstate spectroscopy: ringdown, quasinormal modes, and echoes
Taishi Ikeda, Massimo Bianchi, Dario Consoli +4
Deep conceptual problems associated with classical black holes can be addressed in string theory by the ``fuzzball'' paradigm, which provides a microscopic description of a black h…
Dynamical Analysis of Screening in Scalar-Tensor Theory
Tomohiro Nakamura, Taishi Ikeda, Ryo Saito +2
We investigate linear and non-linear dynamics of spherically symmetric perturbations on a static configuration in scalar-tensor theories focusing on the chameleon screening mechani…
Black hole binaries and light fields: Gravitational molecules
Taishi Ikeda, Laura Bernard, Vitor Cardoso +1
We show that light scalars can form quasibound states around binaries. In the nonrelativistic regime, these states are formally described by the quantum-mechanical Schrodinger equa…
Spontaneous scalarization of a conducting sphere in Maxwell-scalar models
Carlos A. R. Herdeiro, Taishi Ikeda, Masato Minamitsuji +2
We study the spontaneous scalarization of a standard conducting charged sphere embedded in Maxwell-scalar models in flat spacetime, wherein the scalar field is nonminimally cou…
Tidal effects and disruption in superradiant clouds: a numerical investigation
Vitor Cardoso, Francisco Duque, Taishi Ikeda
The existence of light, fundamental bosonic fields is an attractive possibility that can be tested via black hole observations. We study the effect of a tidal field -- caused by a…
