Phantom Cosmology with a Nonlinear Born - Infeld type Scalar Field
Recent progress in theoretical physics suggests that the dark energy in the universe result from the Born-Infeld (B-I) type scalar field of string theory. The universe of B-I type scalar field with potential can undergo a phase of accelerated expansion. The corresponding equation of state parameter lies in the range of −1 < w < − 1 3. The equation of state parameter of B-I type scalar field wit...
متن کامل4 Phantom Cosmology with the Born - Infeld Type Scalar Field
We considered the phantom cosmology with the original B-I type scalar Field with the lagrangian L = 1 η [1 − 1 − ηg µν φ , µ φ , ν ] − u(φ),which is proposed by Born and Infeld in 1934. We find that there must exist a positive potential u(ϕ) for physical permit in our phantom model. We give the condition for an arbitrary potential to admit a late time attractor solution and then study a specifi...
متن کاملNon-Abelian Einstein-Born-Infeld-Dilaton Cosmology
The non-abelian Einstein-Born-Infeld-Dilaton theory, which rules the dynamics of tensor-scalar gravitation coupled to a su(2)-valued gauge field ruled by Born-Infeld lagrangian, is studied in a cosmological framework. The microscopic energy exchange between the gauge field and the dilaton which results from a non-universality of the coupling to gravity modifies the usual behaviour of tensor-sca...
متن کاملBorn-Infeld-Einstein theory with matter
The field equations associated with the Born-Infeld-Einstein action including matter are derived using a Palatini variational principle. Scalar, electromagnetic, and Dirac fields are considered. It is shown that an action can be chosen for the scalar field that produces field equations identical to the usual Einstein field equations minimally coupled to a scalar field. In the electromagnetic an...
متن کاملAnisotropic Born-Infeld Cosmologies
Anisotropic cosmological spacetimes are constructed from spherically symmetric solutions to Einstein’s equations coupled to nonlinear electrodynamics and a positive cosmological constant. This is accomplished by finding solutions in which the roles of r and t are interchanged for all r > 0 (i.e. r becomes timelike and t becomes spacelike). Constant time hypersurfaces have topology R × S and in ...
