String field Theory and new cosmological models

Obiettivo

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.
