Running cosmological constant with observational tests
Chao-Qiang Geng, Chung-Chi Lee, Kaituo Zhang
We investigate the running cosmological constant model with dark energy linearly proportional to the Hubble parameter, , in which the CDM limit is recovered by taki…

Matter density perturbation and power spectrum in running vacuum model
Chao-Qiang Geng, Chung-Chi Lee
We investigate the matter density perturbation and power spectrum in the running vacuum model (RVM) with the cosmological constant being a function of the Hubble param…

Deflation of the cosmological constant associated with inflation and dark energy
Chao-Qiang Geng, Chung-Chi Lee
In order to solve the fine-tuning problem of the cosmological constant, we propose a simple model with the vacuum energy non-minimally coupled to the inflaton field. In this model,…
