C-metric like vacuum with non-negative cosmological constant in five dimensions
Liu Zhao, Bin Zhu
We present and analyze an exact 5-dimensional vacuum solution of Einstein equation with non-negative cosmological constant written in a C-metric like coordinate. The metric does no…
Exact solutions of embedding the four-dimensional perfect fluid in a five- or higher-dimensional Einstein spacetime and the cosmological interpretations
Jie Ren, Xin-He Meng, Liu Zhao
We investigate an exact solution that describes the embedding of the four-dimensional (4D) perfect fluid in a five-dimensional (5D) Einstein spacetime. The effective metric of the…
Black chain of pearls in 5D de Sitter spacetime
Liu Zhao
We analyze some exact chain-shaped black hole solutions in 5-dimensional spacetime. Unlike usual black string and black ring solutions, the topology of the horizons of the new solu…
Hamiltonian formalism in Friedmann cosmology and its quantization
Jie Ren, Xin-He Meng, Liu Zhao
We propose a Hamiltonian formalism for a generalized Friedmann-Roberson-Walker cosmology model in the presence of both a variable equation of state (EOS) parameter and a var…
Non-uniform Black Strings with Schwarzschild-(Anti-)de Sitter Foliation
Liu Zhao, Kai Niu, Bing-Shu Xia +2
We present some exact non-uniform black string solutions of 5-dimensional pure Einstein gravity as well as Einstein-Maxwell-dilaton theory at arbitrary dilaton coupling. The soluti…
Tunnelling through black rings
Liu Zhao
Hawking radiation of black ring solutions to 5-dimensional Einstein-Maxwell-dilaton gravity theory is analyzed by use of the Parikh-Wilczek tunnelling method. To get the correct tu…
