Effective constraints and physical coherent states in quantum cosmology: a numerical comparison
Effective constraints and physical coherent states in quantum cosmology: a numerical comparison
A cosmological model with a cyclic interpretation is introduced, which is subject to quantum back-reaction and yet can be treated rather completely by physical coherent states as well as effective constraint techniques. By this comparison, the role of quantum back-reaction in quantum cosmology is unambiguously demonstrated. Also the complementary nature …
