Vacuum Theory

Using the logarithmic superfluid model of physical vacuum, one can formulate an essentially quantum post-relativistic theory, which successfully recovers Einstein’s theory of relativity in low-momenta limit, but otherwise has different foundations and predictions. We present an analytical example of the dispersion relation and show that it should have a Landau form which ensures the suppression of dissipative fluctuations. We show that in the low-momentum sector of the theory, a dispersion relation becomes relativistic with small deformations, such that a photon acquires effective mass, but a much more complex picture arises at large momenta.

Three Components

An attempt is made to present a quasar structure based on the presence in its center of a supermassive object with an accretion disk, as well as the mechanisms for generating jet components and their initial segments. Model jet built on the basis of the allocation of the three main sources of matter supplied to the ejected jet. Such sources are: the baryonic matter of the accretion disk, the matter of the central body of the galaxy and dark galactic matter. Particles of dark matter — bosons — appear as a result of the pairwise combination of microwave photons, which are the remnant of stellar radiation. Deeper levels of matter (physical vacuum, or ether) are not taken into account, but their respective contributions are indicated in appropriate places. The central galactic body is considered an open system (dark star Mitchell - Laplace). This object has a finite size, finite density, and can have a large internal energy. Giving the central body the status of an open system allows one to overcome some difficult moments in the interpretation of observational data concerning the initial parts of the jet. The spatial separation of the original sources of matter makes it possible to speak of three components at the base of the jet of the active galactic nucleus.However, the appearance of a jet with three components requires certain conditions in the galactic core, which are not always there, but can occasionally appear. In addition, despite the fact that for the middle and central components of the jet the mechanism of their formation is the same, the central component of the jet may be absent. For its appearance, it is necessary that the energy and dynamic parameters of the central galactic body and the accretion disk satisfy certain conditions. Removing the restriction on the speed of motion of particles with a nonzero rest mass leads to a simple explanation of the presence of hard radiation from blazars and the appearance of excessively high energies of cosmic particles entering the earth's atmosphere. The consequences resulting from the mechanism of formation of two internal components of the jet are given.Two of them can be checked on the radiation of the central regions of nearby galaxies, and the other two consequences can relate to events on our planet — known major catastrophes and to the phenomenon sometimes observed in the Earth’s atmosphere

Area Law

Within the domain model of QCD vacuum the properties of a statistical ensemble of almost everywhere homogeneous Abelian (anti-)self-dual gluon fields representing the physical vacuum of quantum chromodynamics are investigated. The two-point correlation function of the topological charge density is calculated and the topological susceptibility is found. It is shown that such vacuum fields ensure the implementation of the area law for the Wilson loop, i.e. the confinement of static quarks.

New Phase

In quantum gravity perturbation theory in Newton’s constant G is known to be badly divergent, and as a result not very useful. Nevertheless, some of the most interesting phenomena in physics are often associated with non-analytic behavior in the coupling constant and the existence of nontrivial quantum condensates. It is therefore possible that pathologies encountered in the case of gravity are more likely the result of inadequate analytical treatment, and not necessarily a reflection of some intrinsic insurmountable problem. The nonperturbative treatment of quantum gravity via the Regge–Wheeler lattice path integral formulation reveals the existence of a new phase involving a nontrivial gravitational vacuum condensate, and a new set of scaling exponents characterizing both the running of G and the long-distance behavior of invariant correlation functions. The appearance of such a gravitational condensate is viewed as analogous to the (equally nonperturbative) gluon and chiral condensates known to describe the physical vacuum of QCD. The resulting quantum theory of gravity is highly constrained, and its physical predictions are found to depend only on one adjustable parameter, a genuinely nonperturbative scale ξ in many ways analogous to the scaling violation parameter Λ M ¯ S of QCD. Recent results point to significant deviations from classical gravity on distance scales approaching the effective infrared cutoff set by the observed cosmological constant. Such subtle quantum effects are expected to be initially small on current cosmological scales, but could become detectable in future high precision satellite experiments.
