Vacuum energy problem in anti-de Sitter space
E. V. Arbuzova, A. D. Dolgov
We investigate the cosmological evolution of a universe with an initially large negative vacuum energy, corresponding to an anti-de Sitter (AdS) space-time. Such a universe inevita…
Dynamical mechanism of vacuum energy compensation
E. V. Arbuzova, A. D. Dolgov
The model of vacuum energy compensation due to interaction of a scalar field with curvature scalar of the form is proposed. It is shown that with a simple power…
Problems of spontaneous and gravitational baryogenesis
E. V. Arbuzova, A. D. Dolgov
Spontaneous and closely related to it gravitational baryogenesis are critically analyzed. It is shown that the coupling of the curvature scalar to baryonic current, which induces n…
Intrinsic problems of gravitational baryogenesis
E. V. Arbuzova, A. D. Dolgov
Modification of gravity due to the curvature dependent term in the gravitational baryogenesis scenario is considered. It is shown that this term leads to the fourth order different…
