Construction of Exact Solutions in Two-Fields Models and the Crossing of the Cosmological Constant Barrier
Construction of Exact Solutions in Two-Fields Models and the Crossing of the Cosmological Constant Barrier
A dark energy model with a phantom scalar field, an usual scalar field and the string field theory inspired polynomial potential has been constructed. A two-parameter set of exact solutions to the Friedmann equations has been found. We have constructed such string inspired potential that some exact solutions correspond to …
