Description
The quantum bounce a priori connects several (semi)classical epochs of Universe evolution,
however determining if and how well the semiclassicality is preserved in this transition
is highly nontrivial. We review the present state of knowledge in that regards in the
isotropic sector of loop quantum cosmology. This knowledge is next extended by studies
of an isotropic universe admitting positive cosmological constant (featuring an infinite chain of large Universe epochs). It is also shown, that such universe always admits
a semiclassical epoch thanks to spontaneous spontaneous coherence, provided it is semiclassical in certain constant of motion playing the role of energy.
