TL;DR: In this paper, the role of dust reference fields on cosmological perturbations around a classical spatially flat Friedmann-Lema-tre-Robertson-Walker (FLRW) universe is investigated.

TL;DR: In this article, the authors compare the primordial scalar power spectra in the loop cosmological models using the effective dynamics of the hybrid approach, in which the background is loop quantized, but the perturbations are Fock quantized.

TL;DR: In this paper, the authors analytically investigate the Schwinger pair production in the de Sitter background by using the uniform asymptotic approximation method, and show that the equation of motion in general has two turning points, and the nature of these points could be single, double, real or complex, depending on the choice of the free parameters involved in the theory.

TL;DR: In this article, the authors studied the quantization of the ($1+1$)-dimensional projectable Ho-ifmmode, and found that the system can be quantized by following the canonical Dirac quantization, and the corresponding wave function is normalizable for some orderings of the operators.

TL;DR: In this paper, a reduced phase space quantization of loop quantum cosmology with Gaussian and Brown-Kuchař dust, and massless Klein-Gordon scalar reference fields for a spatially flat FLRW model with a Starobinsky inflationary potential is presented.
