Dark energy from a gas of thin tubes of a massless scalar field

In this work, we investigated the influence on the evolution of gas of thin tubes of a massless scalar field, in particular, on its ability to accelerated expansion, of such characteristics of thin tubes forming gas as thickness (core radius), the moment of their formation and spatial shape. The study showed that the formation of thin tubes of a scalar field that form gas becomes possible only some time after the singular state of the Universe. At the same time, the thinner the tubes form a gas, and the later in the process of evolution they were formed, the faster such a gas can achieve the equation of state [Formula: see text].
