Bottom-up open EFT for non-Abelian gauge theory with dynamical color environment
Yoshihiko Abe, Kanji Nishii
We develop a bottom-up open effective field theory (EFT) for non-Abelian gauge theories within the Schwinger--Keldysh formalism. Instead of integrating out the environment complete…
Perturbative unitarity bounds on field-space curvature in de Sitter spacetime: purity vs scattering amplitude
Qianhang Cai, Tomoya Inada, Masataka Ishikawa +2
We study perturbative unitarity bounds on the field-space curvature in de Sitter spacetime, using the momentum-space entanglement approach recently proposed by Duaso Pueyo, Goodhew…
Apparent Horizons Associated with Dynamical Black Hole Entropy
Hideo Furugori, Kanji Nishii, Daisuke Yoshida +1
We define entropic marginally outer trapped surfaces (E-MOTSs) as a generalization of apparent horizons. We then show that, under first-order perturbations around a stationary blac…
Gravitational EFT for dissipative open systems
Pak Hang Chris Lau, Kanji Nishii, Toshifumi Noumi
We elaborate on the effective field theory (EFT) construction for dissipative open systems coupled to dynamical gravity, in light of recent developments on the EFT of dissipative h…
