Macroscopic effect of quantum gravity: graviton, ghost and instanton condensation on horizon scale of the Universe
Leonid Marochnik, Daniel Usikov, Grigory Vereshkov
We discuss a special class of quantum gravity phenomena that occur on the scale of the Universe as a whole at any stage of its evolution. These phenomena are a direct consequence o…
Dark energy from instantons
Leonid Marochnik
We show that in imaginary time quantum metric fluctuations of empty space form a self-consistent de Sitter gravitational instanton that can be thought of as describing tunneling fr…
Quantum gravity in Heisenberg representation and self-consistent theory of gravitons in macroscopic spacetime
Grigory Vereshkov, Leonid Marochnik
The first mathematically consistent exact equations of quantum gravity in the Heisenberg representation and Hamilton gauge are obtained. It is shown that the path integral over the…
Graviton, ghost and instanton condensation on horizon scale of the Universe. Dark energy as a macroscopic effect of quantum gravity
Leonid Marochnik, Daniel Usikov, Grigory Vereshkov
We show that cosmological acceleration, Dark Energy (DE) effect is a consequence of the zero rest mass, conformal non-invariance of gravitons, and 1-loop finiteness of quantum grav…
Cosmological Acceleration from Virtual Gravitons
Leonid Marochnik, Daniel Usikov, Grigory Vereshkov
Intrinsic properties of the space itself and quantum fluctuations of its geometry are sufficient to provide a mechanism for the acceleration of cosmological expansion (dark energy…
Invariant dynamics of scalar perturbations of inflanton and gravitational fields
O. Lalakulich, L. Marochnik, G. Vereshkov
A gauge-independent, invariant theory of linear scalar perturbations of inflation and gravitational fields has been created. This invariant theory allows one to compare gauges used…
