Decaying vacuum energy, matter creation and cosmic acceleration
Lokesh Chander, C P Singh
We discuss an interacting dark sector model featuring decaying vacuum energy and dark matter empowered by gravitationally induced matter creation. Motivated by quantum field theore…

Exploring interacting bulk viscous model with decaying vacuum density
Vinita Khatri, C. P. Singh, Milan Srivastava
In the present work, we study a cosmological model composed of a viscous dark matter interacting with decaying vacuum energy in a spatially flat Universe. In the first part, we fin…

Holographic Dark Energy Model in Brans-Dicke Theory with Future Event Horizon
Milan Srivastava, C. P. Singh
In this paper, we study the dynamics of non-interacting and interacting holographic dark energy models in the framework of Brans-Dicke theory. As system's infra-red cut-off we cons…
