Thick de Sitter brane solutions in higher dimensions
Vladimir Dzhunushaliev, Vladimir Folomeev, Masato Minamitsuji
We present thick de Sitter brane solutions which are supported by two interacting {\it phantom} scalar fields in five-, six- and seven-dimensional spacetime. It is shown that for a…
Non-singular solutions to Einstein-Klein-Gordon equations with a phantom scalar field
Vladimir Dzhunushaliev, Vladimir Folomeev, Ratbay Myrzakulov +1
It is shown that the 4D Einstein-Klein-Gordon equations with a phantom scalar field (a scalar field with a negative sign in front of the kinetic energy term of its Lagrange density…
Phantom thick brane in 5D bulk
Vladimir Dzhunushaliev, Vladimir Folomeev, Shynaray Myrzakul +1
A model of a thick brane in 5D bulk supported by two phantom scalar fields is considered. The comparison with a thick brane supported by two usual scalar fields is carried out. The…
