One-loop quantum gravity repulsion in the early Universe
Bogusław Broda
Perturbative quantum gravity formalism is applied to compute the lowest order corrections to the classical spatially flat cosmological FLRW solution (for the radiation). The presen…

Bianchi I model in terms of nonstandard loop quantum cosmology: Quantum dynamics
Przemyslaw Malkiewicz, Wlodzimierz Piechocki, Piotr Dzierzak
We analyze the quantum Bianchi I model in the setting of the nonstandard loop quantum cosmology. Elementary observables are used to quantize the volume operator. The spectrum of th…

Spontaneous symmetry breaking for long-wave gravitons in the early Universe
A. A. Grib, V. Yu. Dorofeev
It is shown that nonlinear terms in equations of gravitons on the background of curved space-time of the expanding Universe can solve the problem of the negative square of the effe…
