DESCRIPTION:Speakers: Ashot Gevorkyan (Institute for Informatics and Autom
ation Problems\, NAS of Armenia\, Institute of Chemical Physics\, NAS of A
rmenia)\nAs is well known\, in quantum field theory (QFT) the quantum vacu
um (QV) is\nrepresented as an infinite set of different fluctuating virtua
l particles\nand fields in four-dimensional Minkowski space-time. In this
connection\, a\nnatural question arises: what is the structure of QV\, whe
n the latter is\nin a state of statistical equilibrium and there is no ext
ernal influence\non it? It is obvious that satisfactory answers to these
non-trivial\nquestions we can obtained only within the framework of non-p
erturbative\nquantum field models. In this paper\, we consider the quantum
equation of a\nmassless field in the fluctuating four-dimensional Minkows
ki space-time\,\nwhich is equivalent to an uncountable-dimensional space-t
ime. As the basic\nequation is used the Langevin type stochastic matrix eq
uation\, regardless\nof the formalism of second quantization. It is assume
d that\, on small\nfour-dimensional space-time intervals\, the quantum fie
ld equation\ncoincides with a regular matrix equation analogous to the Wey
l equation\nfor a neutrino. It is proved that in the statistical equilibri
um limit the\ninitial uncountable space-time is reduced to a ten-dimension
al space-time\,\nwhere four dimensions are Minkowski space-time\, and the
remaining six\ndimensions are compact topological subspaces. In detail is
studied\nconditions of quantization of vacuum fields in compact subspaces
and it is\nshown that these quantized states can claim the role of dark en
ergy. It is\nshown that even weak external electromagnetic fields are capa
ble of\ndeforming compact subspaces\, because of which the refractive indi
ces of a\nvacuum can vary measurably. The latter\, in particular\, means t
hat the\ndeveloped representation allows for the existence of a new mechan
ism of\ninteraction between photons through the deformation of compact sub
spaces\,\nwhich is fundamentally differ from the usual mechanisms of phot
on-photon\nscattering\, described by the fourth order Feynman's diagram
