Inflationary magnetogenesis with a self-consistent coupling function
Y. Li, L. Y. Zhang
In this paper, we discuss the inflationary magnetogenesis scenario, in which the coupling function is introduced to break the conformal invariance of electromagnetic action. Unlike…
Dynamics of two-scalar-field cosmological models beyond the exponential potential
Yu Li
In this paper, we discuss the dynamics of two- scalar-field cosmological models. Unlike in the situation of exponential potential, we find that there are late-time attractors in wh…
Adiabatic and non-adiabatic perturbations for loop quantum cosmology
Yu Li, Jian-Yang Zhu
We generalize the perturbations theory of loop quantum cosmology to a hydrodynamical form and define an effective curvature perturbation on an uniform density hypersurfaces .…
Application of higher order holonomy corrections to perturbation theory of cosmology
Yu Li, Jian-Yang Zhu
Applying the higher order holonomy corrections to the perturbation theory of cosmology, the lattice power law of Loop Quantum Cosmology, , is analysed and the r…
Convergence of Perturbations for a Big Bounce in Loop Quantum Cosmology
Yu Li, Jian-Yang Zhu
We investigate the convergence behaviors of the scalar and the vector perturbations for a big bounce phase in loop quantum cosmology. Two models are discussed: one is the universe…
