A new gravitational black-hole
M. Novello, A. E. S. Hartmann
In a recent paper we have analyzed the Spinor Theory of Gravity (STG) which is based on the intimate relation between Fermi (weak) interaction and gravity. We presented the hypothe…
A new bifurcation in the Universe
A. E. S. Hartmann, M. Novello
We show that the combined system of general relativity with a non minimally coupled electromagnetic field presents a bifurcation in a cosmical framework driven by a cosmological co…
The cosmological constant and a scalar field coupled non minimally to gravity
M. Novello, A. E. S. Hartmann
We show that the combined minimal and non minimal interaction with the gravitational field may produce the generation of a cosmological constant without self-interaction of the sca…
Is the electromagnetic field responsible for the cosmic acceleration in late times?
M. Novello, A. E. S. Hartmann
We show that in the realm of general relativity a non minimal coupling between the electromagnetic and the gravitational fields may produce an era of accelerated expansion.
