Gravitational Baryogenesis in Rainbow Gauss-Bonnet gravity
P. Goodarzi, H. Mohseni Sadjadi, R. Darabi
The paper investigates how combining rainbow gravity with a four‑dimensional Einstein–Gauss–Bonnet model can generate a non‑zero time derivative of the Ricci scalar during the radi…

Chaos bound violation by spinning particles in Gauss-Bonnet-AdS black holes
Xiaowei Li, Mengxuan Wu, Guoping Li
The paper examines how spinning test particles in Gauss‑Bonnet anti‑de Sitter black holes can violate the chaos bound, showing that the Lyapunov exponent depends on particle spin,…

Scalarization of Charged Black Hole in Gauss-Bonnet Extended Starobinsky-Maxwell Gravity
Rui-Xi Zhu, Hai-Shan Liu
The paper studies how black holes can develop scalar hair in a theory that combines Starobinsky gravity with a Gauss‑Bonnet term, revealing a new multi‑branch structure of solution…
