High-order quantum back-reaction and quantum cosmology with a positive cosmological constant
High-order quantum back-reaction quantum cosmology positive cosmological constant

When quantum back-reaction by fluctuations, correlations and higher moments of a state becomes strong, semiclassical quantum mechanics resembles a dynamical system with a high-dimensional phase space....
Observables for FRW model with cosmological constant in the framework of loop cosmology
cosmological constant framework of loop cosmology
2010/3/18
We consider a flat cosmological model with a free massless scalar field and the cosmological constant $\Lambda$ in the framework of loop quantum cosmology. The scalar field plays the role of an intrin...
