Coupled phantom cosmological model motivated by the warm inflationary paradigm
Sudip Halder, Supriya Pan, Paulo M. Sá +1
In this article, we investigate a coupled phantom dark-energy cosmological model in which the coupling term between a phantom scalar field with an exponential potential and a press…

Coupled quintessence inspired by warm inflation
Paulo M. Sá
We investigate a coupled quintessence cosmological model in which a dark-energy scalar field with an exponential potential interacts directly with a dark-matter fluid through a dis…
