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…

High-order Primordial Perturbations with Quantum Gravitational Effects
Tao Zhu, Anzhong Wang, Klaus Kirsten +2
In this paper, we provide a systematic investigation of high-order primordial perturbations with nonlinear dispersion relations due to quantum gravitational effects in the framewor…
