Exact dynamics and the spin wall for large-spin particles in Schwarzschild spacetime
Chao-Jun Feng, Rui-Hui Lin
The motion of a spinning test particle in a curved spacetime is governed by the Mathisson--Papapetrou--Dixon (MPD) equations and deviates from geodesic motion already at first orde…

Dynamical analysis of the H^2 + H^-2 Dark Energy model considering viscosity and interaction
Guo Chen, Wei Fang, Chao-Jun Feng
In this study, we further developed and investigated the dual parameter phenomenological dark energy model (H^2 + H^-2 dark energy model) derived from Kaniadakis holographic dark e…

Thermodynamics of the Dark Energy model
Guo Chen, Chao-Jun Feng, Wei Fang +1
In this study, we introduced a phenomenological dark energy model model) that incorporates the first-order approximation of Kaniadakis holographic entropy dark energ…
