Perturbative stability of SFT-based cosmological models
Federico Galli, Alexey S. Koshelev
We review the appearance of multiple scalar fields in linearized SFT based cosmological models with a single non-local scalar field. Some of these local fields are canonical real s…

Multi-scalar field cosmology from SFT: an exactly solvable approximation
Federico Galli, Alexey S. Koshelev
We consider the appearance of multiple scalar fields in SFT inspired non-local models with a single scalar field at late times. In this regime all the scalar fields are free. This…

Analysis of scalar perturbations in cosmological models with a non-local scalar field
Alexey S. Koshelev, Sergey Yu. Vernov
We develop the cosmological perturbations formalism in models with a single non-local scalar field originating from the string field theory description of the rolling tachyon dynam…
