Wave-like exact models with symmetry of spatial homogeneity in the quadratic theory of gravity with a scalar field
K. E. Osetrin, I. V. Kirnos, E. K. Osetrin +1
Exact solutions are obtained in the quadratic theory of gravity with a scalar field for wave-like models of space-time with spatial homogeneity symmetry and allowing the integratio…
Accelerating and decelerating cosmology from spinor and scalar fields non-minimally coupled with f(R) gravity
Yu. A. Rybalov, A. N. Makarenko, K. E. Osetrin
In this paper we investigate the accelerating and decelerating cosmological models with non-linear spinor fields and non-minimal interaction of gravity with a scalar field.…
Dynamical Casimir Effect and Quantum Cosmology
I. Brevik, K. A. Milton, S. D. Odintsov +1
We apply the background field method and the effective action formalism to describe the four-dimensional dynamical Casimir effect. Our picture corresponds to the consideration of q…
Can primordial wormholes be induced by GUTs at the early Universe?
S. Nojiri, O. Obregon, S. D. Odintsov +1
Using large N, 4d anomaly induced one-loop effective action for conformally invariant matter (typical GUT multiplet) we study the possibility to induce the primordial spherically s…
(Non) singular Kantowski-Sachs Universe from quantum spherically reduced matter
S. Nojiri, O. Obregon, S. D. Odintsov +1
Using s-wave and large N approximation the one-loop effective action for 2d dilaton coupled scalars and spinors which are obtained by spherical reduction of 4d minimal matter is fo…
Induced wormholes due to quantum effects of spherically reduced matter in large N approximation
S. Nojiri, O. Obregon, S. D. Odintsov +1
Using one-loop effective action in large N and s-wave approximation we discuss the possibility to induce primordial wormholes at the early Universe. An analytical solution is found…
