Equivalence between generalized phenomenological schemes for the interaction of cosmological fluids: applications to arbitrary linear barotropic fluids and vacuum decay
M. R. G. Maia, N. Pires, H. S. Gimenes
Interactions between cosmic fluids may appear in many cosmological scenarios that go far beyond the usually studied energy exchange in the dark sector. In the absence of known micr…
Inhomogeneus Inflation and Cosmic no-Hair Conjecture
M. A. S. Nobre, M. R. de Garcia Maia, J. C. Carvalho +1
The cosmic no hair conjecture is tested for a large class of inhomogeneous cosmologies with a positive cosmological constant. Firstly, we derive a new class of exact inhomogeneous…
Nonsingular FRW cosmology and nonlinear electrodynamics
C. S. Camara, M. R. de Garcia Maia, J. C. Carvalho +1
The possibility to avoid the cosmic initial singularity as a consequence of nonlinear effects on the Maxwell eletromagnetic theory is discussed. For a flat FRW geometry we derive t…
Quantum corrections to Maxwell electrodynamics in a homogeneous and isotropic universe with cosmological constant
M. R. de Garcia Maia, J. C. Carvalho, C. S. da Câmara Neto
Some cosmological consequences of first order quantum corrections to Maxwell electrodynamics are investigated in the context of a spatially flat homogeneous and isotropic universe…
