Spin-mediated modulation of chaos bound violation in Lorentz-violating black hole spacetimes
Chuang Yang, Deyou Chen, Bingbing Chen
We investigate how the particle spin modulates chaos bound violations in Lorentz-violating black hole spacetimes within the framework of Bumblebee gravity. Using the Mathisson-Papa…

Testing the chaos bound in the spinor field of Einstein-Euler-Heisenberg-Anti-de Sitter spacetime
Xiaowei Li, Bingbing Chen, Guoping Li
Violations of the chaos bound have been observed in scalar fields. In this work, we investigate the Lyapunov exponents of chaotic particles in the spinor field of an Einstein-Euler…
