Crossing of the w=-1 Barrier by D3-brane Dark Energy Model
I. Ya. Aref'eva, A. S. Koshelev, S. Yu. Vernov
We explore a possibility for the Universe to cross the w=-1 cosmological constant barrier for the dark energy state parameter. We consider the Universe as a slowly decaying D3-bran…
Stringy Dark Energy Model with Cold Dark Matter
I. Ya. Aref'eva, A. S. Koshelev, S. Yu. Vernov
Cosmological consequences of adding the Cold Dark Matter (CDM) to the exactly solvable stringy Dark Energy (DE) model are investigated. The model is motivated by the consideration…
Exactly Solvable SFT Inspired Phantom Model
I. Ya. Aref'eva, A. S. Koshelev, S. Yu. Vernov
An exact solution to the Friedmann equations with a string inspired phantom scalar matter field is constructed and the absence of the "Big Rip" singularity is shown explicitly. The…
