A study on Cubic Galileon Gravity Using N-body Simulations
Jiajun Zhang, Bikash R. Dinda, Md. Wali Hossain +2
We use N-body simulation to study the structure formation in the Cubic Galileon Gravity model where along with the usual kinetic and potential term we also have a higher derivative…
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…
Bigravity and Horndeski gravity connected by a disformal coupling
Radouane Gannouji, Md. Wali Hossain, Nur Jaman +1
In this paper, we have studied bi-gravity theory in a very specific limit where we focused only on one degree of freedom generated by the massive graviton. We have analyzed the mod…
Quintessential inflation: A unified scenario of inflation and dark energy
Md. Wali Hossain
Quintessential inflation unifies inflation and late time acceleration by a single scalar field. Such a scenario, with canonical and non-canonical scalar fields, has been discussed…
