Perturbations in loop quantum cosmology [PDF]

arXiv, 2012
The era of precision cosmology has allowed us to accurately determine many important cosmological parameters, in particular via the CMB. Confronting Loop Quantum Cosmology with these observations provides us with a powerful test of the theory. For this to be possible we need a detailed understanding of the generation and evolution of inhomogeneous ...

Cosmological Constant from Equivalent Transformation in Quantum Cosmology [PDF]

arXiv
We explore the introduction of the cosmological constant via equivalent transformations in cosmology. We consider the Wheeler-DeWitt equation for the CDM universe and we construct the Hamilton-Jacobi action for the $\Lambda$CDM model. We discuss how this approach allows us to relate different physical systems, providing insights into the role of the ...
