Ja n 20 05 Quantum driven Bounce of the Universe near Sudden Future Singularity

چکیده

It is demonstrated that due to back-reaction of quantum effects, expansion of the universe stops at its maximum and takes a turn around. Later on, it contracts to a very small size in finite future time. This phenomenon is followed by a " bounce " with rebirth of an exponentially expanding non-singular universe. It is explored that this exponential expansion may stop at some time after bounce, as it is expected for inflationary models of the early universe.

Taking quantum effects of conformal fields into account, it is shown that future universe may escape from phantom menace when w< −1. It is demonstrated that due to back-reaction of quantum effects, expansion of the universe stops at its maximum and takes a turnaround. Later on, it contracts to a very small size in finite future time. This phenomenon is followed by a " bounce " with rebirth of a...

A pr 2 00 5 Non - violation of Energy Conditions in the future accelerated universe due to quantum effects

Here, an accelerated phantom model for the late universe is explored, which is free from future singularity. It is interesting to see that this model exhibits strong curvature for all time in future, unlike models with 'sudden future singularity' showing high curvature near singularity time only. So, quantum gravity effects be dominant as time increses in late universe too. More importantly, it...

On the Big Bounce Singularity of a Simple 5D Cosmological Model

The big bounce singularity of a simple 5D cosmological model is studied. Contrary to the standard big bang space-time singularity, this big bounce singularity is found to be an event horizon at which the scale factor and the mass density of the universe are finite, while the pressure undergoes a sudden transition from negative infinity to positive infinity. By using coordinate transformation it...

Inflationary universe in loop quantum cosmology

Loop quantum cosmology provides a nice solution of avoiding the big bang singularity through a big bounce mechanism in the high energy region. In loop quantum cosmology an inflationary universe is emergent after the big bounce, no matter what matter component is filled in the universe. A super-inflation phase without phantom matter will appear in a certain way in the initial stage after the bou...
