Effective Field Theory of Black Hole Perturbations in Vector-Tensor Gravity
Katsuki Aoki, Mohammad Ali Gorji, Shinji Mukohyama +2
We formulate the effective field theory (EFT) of vector-tensor gravity for perturbations around an arbitrary background with a vector profile, which can be applied…
Effective Field Theory of Gravitating Continuum: Solids, Fluids, and Aether Unified
Katsuki Aoki, Mohammad Ali Gorji, Shinji Mukohyama +1
We investigate the relativistic effective field theory (EFT) describing a non-dissipative gravitating continuum. In addition to ordinary continua, namely solids and fluids, we find…
The Effective Field Theory of Vector-Tensor Theories
Katsuki Aoki, Mohammad Ali Gorji, Shinji Mukohyama +1
We investigate a systematic formulation of vector-tensor theories based on the effective field theory (EFT) approach. The input of our EFT is that the spacetime symmetry is spontan…
Cosmic No-hair Conjecture and Inflation with an SU(3) Gauge Field
Pengyuan Gao, Kazufumi Takahashi, Asuka Ito +1
We study inflationary universes with an SU(3) gauge field coupled to an inflaton through a gauge kinetic function. Although the SU(3) gauge field grows at the initial stage of infl…
Effective Field Theory of Anisotropic Inflation and Beyond
Jinn-Ouk Gong, Toshifumi Noumi, Gary Shiu +3
We develop an effective-field-theory (EFT) framework for inflation with various symmetry breaking pattern. As a prototype, we formulate anisotropic inflation from the perspective o…
