Накратко на български
Космологични модели, базирани на теорията за стринговите полета, анализират явления като тъмната енергия. Тези проучвания помагат за по-доброто разбиране на развитието на Вселената и стабилността на нейните физични сценарии.

Final Activity Report Summary - STRING COSMOLOGY (String Field Theory and new Cosmological Models)
Scalar non-local cosmologies were studied and general properties of such models were established and investigated. It was shown that the non-local string field theory tachyon provided cosmological models that were very interesting from the modern point of view and capable to describe various observed phenomena including dark energy. Apart from that, these models exhibited many features that could be appreciated in real cosmological scenarios. An explicitly covariant formulation was also presented of a modified Dvali-Gabadadze-Porrati (DGP) cosmological scenario which was recently proposed, in order to avoid the instability of the self-accelerating branch.

Цел на проекта
New cosmological models arising from String Field Theory will be studied. It is known from observational data that the state parameter w in cosmology is close to -1. It is suggested to use the tachyon of string field theory as a scalar field in cosmological models of the Dark Energy, because the non-local structure of the string interaction makes this field a phantom, which would realize the Dark Energy dominated Universe. Various consequences of these new cosmological models, such as an interaction with the Cold Dark Matter, brane decay in the non-flat gravitational background and brane-world scenarios will be studied in the light of new ideas coming from String Field Theory. Relationships with the bulk-boundary correspondence and the concept of brane cosmology will also be studied.
