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…
Spherically symmetric selfdual Yang-Mills instantons on curved backgrounds in all even dimensions
Eugen Radu, D. H. Tchrakian, Yisong Yang
We present several different classes of selfdual Yang-Mills instantons in all even d backgrounds with Euclidean signature. In d=4p+2 the only solutions we found are on constant cur…
Birefringence and non-transversality of light propagation in an ultra-strongly magnetized vacuum
Shuang-Wei Hu, Bin-Bin Liu
The birefringence phenomenon in the vacuum with a constant magnetic background of arbitrary strength is considered within the framework of the effective action approach. A new feat…
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…
