Scalar fields with power-law potentials in quantum cosmology
V. E. Kuzmichev, V. V. Kuzmichev
A homogeneous and isotropic quantum cosmological system (universe) initially filled with a uniform scalar field that has a potential in the power law representation is considered.…
On primordial matter production induced by spatial curvature in the early universe
V. E. Kuzmichev, V. V. Kuzmichev
In this note, it is shown that nonvanishing spatial curvature produces primordial matter in the initially empty universe due to quantum gravity effects. This matter decays faster t…
Cosmology with the matter component decaying faster than radiation
V. E. Kuzmichev, V. V. Kuzmichev
The impact of a fast decaying component of mass-energy, that decreases faster than radiation with the increase of the scale factor, on the evolution of the universe is studied usin…
Minisuperspace model of quantum geometrodynamics in the Madelung-Bohm formalism
V. E. Kuzmichev, V. V. Kuzmichev
An analogy between non-relativistic quantum mechanics in the Madelung formulation and quantum geometrodynamics in the case of the maximally symmetric space is drawn. The equations…
The Hubble tension from the standpoint of quantum cosmology
V. E. Kuzmichev, V. V. Kuzmichev
The Hubble tension is analyzed in the framework of quantum cosmological approach. It is found that there arises a new summand in the expression for the total energy density stipula…
On the conditions for the classicality of a quantum particle
V. E. Kuzmichev, V. V. Kuzmichev
Conditions under which a quantum particle is described using classical quantities are studied. The one-dimensional (1D) and three-dimensional (3D) problems are considered. It is sh…
