Classification of Cosmological Trajectories
Qi Guo, Rong-Gen Cai
In the context of effective Friedmann equation we classify the cosmologies in multi-scalar models with an arbitrary scalar potential according to their geometric properties. It…
Cosmological Evolution of Interacting Phantom Energy with Dark Matter
Zong-Kuan Guo, Rong-Gen Cai, Yuan-Zhong Zhang
We investigate the cosmological evolution of an interacting phantom energy model in which the phantom field has interaction with the dark matter. We discuss the existence and stabi…
Acoustic Wormholes
Kamal Kanti Nandi, Yuan-Zhong Zhang, Rong-Gen Cai
Acoustic analogs of static, spherically symmetric massive traversable Lorentzian wormholes are constructed as a {\em formal} extension of acoustic black holes. The method is straig…
Generalized Milne Space, Eternal Accelerating Cosmology, Ep-branes and dS/CFT Correspondence
Rong-Gen Cai, Anzhong Wang
This paper has been withdrawn by the authors due to the existence of main results in the literature.
A Note on Thermodynamics of Black Holes in Lovelock Gravity
Rong-Gen Cai
The Lovelock gravity consists of the dimensionally extended Euler densities. The geometry and horizon structure of black hole solutions could be quite complicated in this gravity,…
Cosmological Scaling Solutions and Cross-coupling Exponential Potential
Zong-Kuan Guo, Yun-Song Piao, Rong-Gen Cai +1
We present a phase-space analysis of cosmology containing multiple scalar fields with a positive or negative cross-coupling exponential potential. We show that there exist power-la…
