A general maximum entropy principle for self-gravitating perfect fluid
Sijie Gao
We consider a self-gravitating system consisting of perfect fluid with spherical symmetry. Using the general expression of entropy density, we extremize the total entropy under…
Particle collisions near the cosmological horizon of a Reissner-Nordström de Sitter black hole
Changchun Zhong, Sijie Gao
It has recently been shown that black holes can act as particle accelerators and two particles can collide with arbitrarily high center-of-mass (CM) energy under certain critical c…
Non-extremal Kerr black holes as particle accelerators
Sijie Gao, Changchun Zhong
It has been shown that extremal Kerr black holes can be used as particle accelerators and arbitrarily high energy may be obtained near the event horizon. We study particle collisio…
Stability of Brans-Dicke thin shell wormholes
Xiaojun Yue, Sijie Gao
Recently, a class of spherically symmetric thin-shell wormholes in Brans-Dicke gravity have been introduced. Such wormholes can be supported by matter satisfying the weak energy co…
