Dark Energy and Inflation from Gravitational Waves
Leonid Marochnik
In this seven-part paper, we show that gravitational waves (classical and quantum) produce the accelerated de Sitter expansion at the start and at the end of the cosmological evolu…
Cosmological Acceleration from Scalar Field and Classical and Quantum Gravitational Waves (Dark Energy and Inflation)
Leonid Marochnik
We show that on the average, homogeneous and isotropic scalar field and on the average homogeneous and isotropic ensembles of classical and quantum gravitational waves generate the…
Cosmological Acceleration from Gravitational Waves
Leonid Marochnik
It is shown that the classical gravitational waves of super-horizon wavelengths are able to form the de Sitter accelerated expansion of the empty (with no matter fields) Universe.…
Dark Energy and Inflation in a Gravitational Wave Dominated Universe
Leonid Marochnik
The empty space (with no matter fields) is not really empty because of natural metric fluctuations, quantum and classical. We show that gravitons as well as classical gravitational…
Invariance of de Sitter State with Respect to Wick Rotation, Inflation and Dark Energy
Leonid Marochnik
It is shown that the de Sitter state is invariant with respect to Wick rotation. In imaginary time, super- horizon quantum and classical metric fluctuations of the empty FLRW space…
Inflation and CMB Anisotropy from Quantum Metric Fluctuations
Leonid Marochnik, Daniel Usikov
We propose a model of cosmological evolution of the early and late Universe which is consistent with observational data and naturally explains the origin of inflation and dark ener…
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…
West-Side Story (On the History of Density-Wave Spiral Theories in the 1960s)
Leonid Marochnik
This paper deals with the history of Density-Wave Spiral Theories in the 1960s. The motivation to write the paper was the publication of two papers on the history of these theories…
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…
