Horizon Entropy in Modified Gravity
Peng Wang
We present an observation about the proposal that four-dimensional modification of general relativity may explain the observed cosmic acceleration today. Assuming that the thermody…

Virialization in Dark Energy Cosmology
Peng Wang
We discuss the issue of energy nonconservation in the virialzation process of spherical collapse model with homogeneous dark energy. We propose an approximation scheme to find the…

Dark Energy: Vacuum Fluctuations, the Effective Phantom Phase, and Holography
Emilio Elizalde, Shin'ichi Nojiri, Sergei D. Odintsov +1
We aim at the construction of dark energy models without exotic matter but with a phantom-like equation of state (an effective phantom phase). The first model we consider is decayi…
