Relating the scalar weak gravity conjecture and the swampland distance conjecture for an accelerating universe
Suddhasattwa Brahma, Md. Wali Hossain
For any quasi de Sitter background, we show that a recently proposed scalar weak gravity conjecture (sWGC) follows from the swampland distance conjecture, together with the covaria…
Dark energy beyond quintessence: Constraints from the swampland
Suddhasattwa Brahma, Md. Wali Hossain
The string theory swampland proposes that there is no UV-completion for an effective field theory with an exact (metastable) de Sitter vacua, thereby ruling out standard CDM cos…
Avoiding the string swampland in single-field inflation: Excited initial states
Suddhasattwa Brahma, Md. Wali Hossain
One class of single-field inflationary models compatible with the recently-conjectured Swampland criteria would be those in which a Hubble slow-roll parameter is not t…
Cosmological investigations of (extended) nonlinear massive gravity schemes with non-minimal coupling
K. Bamba, Md. Wali Hossain, R. Myrzakulov +2
In this paper we investigate the case of non-minimal coupling in the (extended) nonlinear massive gravity theories. We first consider massive gravity in the Brans-Dicke background…
