A Note on Self-gravitating Radiation in AdS Spacetime
Zhong-Hua Li, Bin Hu, Rong-Gen Cai
In this paper we investigate the equilibrium self-gravitating radiation in higher dimensional, plane symmetric anti-de Sitter space. We find that there exist essential differences…
Statefinder Diagnostic and w-w' Analysis for the Agegraphic Dark Energy Models without and with Interaction
Hao Wei, Rong-Gen Cai
A new dark energy model, named as ``agegraphic dark energy'', has been proposed by one of us (R. G. Cai) in arXiv:0707.4049, based on the Károlyházy uncertainty relation, which ari…
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…
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…
