Phantom cosmology with arbitrary potential: New accelerating scaling attractors
Sudip Halder, Supriya Pan, Paulo M. Sá +1
In this article, we investigate the existence of accelerating scaling solutions in coupled phantom cosmology without assuming any specific potential for the phantom scalar field. T…

Matter Creation Cosmologies and Accelerated Expansion
Sudip Halder, Jaume de Haro, Supriya Pan +2
Non-conservation of dark matter can lead to late-time cosmic acceleration. This mechanism is known as the matter creation theory and this replaces the need of dark energy and modif…
