Black Hole Thermodynamics Meets On-Shell Amplitudes: Local Detailed Balance and Thermal Spectrum from Spin Universality and Unitarity
Dogan Akpinar, Katsuki Aoki, Andrea Cristofoli +2
We develop an on-shell framework for thermal dissipation and radiation by macroscopic objects, whose large degeneracy of internal states is encoded in their entropy. In this framew…
Trapped Surface as a Cosmic Censor
Hideo Furugori, Daisuke Yoshida, Kaho Yoshimura
We formulate a local geometric criterion for weak cosmic censorship in black hole overcharging and overspinning thought experiments. Under the null convergence and generic conditio…
Quantum Effects for Black Holes with On-Shell Amplitudes
Katsuki Aoki, Andrea Cristofoli, Hyun Jeong +2
We develop a framework based on modern amplitude techniques to analyze emission and absorption effects in black hole physics, including Hawking radiation. We first discuss quantum…
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…
Causality Constraints on Black Hole Thermodynamics in Nonlinear Electrodynamics
Yoshihiko Abe, Maxime Médevielle, Toshifumi Noumi +1
We study causality constraints on black hole thermodynamics in nonlinear electrodynamics, where the Lagrangian is taken to be an arbitrary function of the electromagnetic field str…
The First Law and Weak Cosmic Censorship for de Sitter Black Holes
Daisuke Yoshida, Kaho Yoshimura
We apply Iyer-Wald's covariant phase space formalism to asymptotically de Sitter spacetimes and establish the thermodynamic first law, expressed in terms of the Abbott-Deser mass.…
Black Hole Extremality in Nonlinear Electrodynamics: A Lesson for Weak Gravity and Festina Lente Bounds
Yoshihiko Abe, Toshifumi Noumi, Kaho Yoshimura
We study black hole extremality in nonlinear electrodynamics motivated by the Weak Gravity Conjecture (WGC) and the Festina Lente (FL) bound. For illustration, we consider the Eule…
