Time Lumps in Nonlocal Stringy Models and Cosmological Applications | | I.Ya.Aref’eva

25 Apr 2005 | | Journal: | JHEP 0510 (2005) 087 | | Subject: | hep-th | | Abstract: | We study lump solutions in nonlocal toy models and their cosmological applications. These models are motivated by a description of D-brane decay within string field theory framework. In order to find cosmological solutions we use the simplest local approximation keeping only second derivative terms in nonlocal dynamics. We study a validity of this approximation in flat background where time lump solutions can be written explicitly. We work out the validity of this approximation. We show that our models at large time exhibit the phantom behaviour similar to the case of the string kink. | | Source: | arXiv, hep-th/0504200 | | Services: | Forum | Review | PDF | Favorites | |
