The primordial angular power spectrum from the alternative mass function in loop quantum cosmology
Abolhassan Mohammadi, Bao-Fei Li, Tao Zhu
We investigate the cosmological impacts of the alternative effective mass function of the modified Mukhanov-Sasaki equation in loop quantum cosmology, which is obtained from the po…

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…
