Challenges for scaling cosmologies
Luca Amendola, Miguel Quartin, Shinji Tsujikawa +1
A cosmological model that aims at solving the coincidence problem should show that dark energy and dark matter follow the same scaling solution from some time onward. At the same t…
Power-laws f(R) theories are cosmologically unacceptable
Luca Amendola, David Polarski, Shinji Tsujikawa
In a recent paper [1] (PRL 98,131302,2007) we have shown that f(R)=R + mu R^{n} modified gravity dark energy models are not cosmologically viable because during the matter era that…
Are f(R) dark energy models cosmologically viable ?
Luca Amendola, David Polarski, Shinji Tsujikawa
All modified gravity theories are conformally identical to models of quintessence in which matter is coupled to dark energy with a strong coupling. This coupling induces a c…
