Preinflationary perturbations from the closed algebra approach in loop quantum cosmology
Bao-Fei Li, Tao Zhu, Anzhong Wang +3
In this paper, the scalar and tensor perturbations in the closed algebra approach of loop quantum cosmology are studied. Instead of the distant past in the contracting phase, we ch…
Qualitative dynamics and inflationary attractors in loop cosmology
Bao-Fei Li, Parampreet Singh, Anzhong Wang
Qualitative dynamics of three different loop quantizations of spatially flat isotropic and homogeneous models is studied using effective spacetime description of the underlying qua…
Towards Cosmological Dynamics from Loop Quantum Gravity
Bao-Fei Li, Parampreet Singh, Anzhong Wang
We present a systematic study of the cosmological dynamics resulting from an effective Hamiltonian, recently derived in loop quantum gravity using Thiemann's regularization and ear…
