(m,n)-type holographic dark energy models    [PDF]

Yi Ling, Wen-Jian Pan

We construct $(m,n)$-type holographic dark energy models at a phenomenological level, which can be viewed as a generalization of agegraphic models with the conformal-like age as the holographic characteristic size. For some values of $(m,n)$ the holographic dark energy can automatically evolve across $\omega=-1$ into a phantom phase even without introducing an interaction between the dark energy and background matter. Our construction is also applicable to the holographic dark energy with generalized future event horizon as the characteristic size.
