Stable initial conditions and analytical investigations of cosmological perturbations in a modified loop quantum cosmology
Rui Pan, Jamal Saeed, Anzhong Wang
In this paper, we study cosmological perturbations in a modified theory of loop quantum cosmologies, the so-called mLQC-I model. Our purposes are two-fold: First, using a method de…

Universal properties of the evolution of the Universe in modified loop quantum cosmology
Jamal Saeed, Rui Pan, Christian Brown +2
In this paper, we systematically study the evolution of the Universe in the framework of a modified loop quantum cosmological model (mLQC-I) with various inflationary potentials, i…

Uniform Asymptotic Approximation Method with Pöschl-Teller Potential
Rui Pan, John Joseph Marchetta, Jamal Saeed +4
In this paper, we study analytical approximate solutions of the second-order homogeneous differential equations with the existence of only two turning points (but without poles), b…
