Kaluza-Klein inspired a model of the inflation with the inversed power law potential in Bianchi type-I universe
Jaturaporn Wattanakumpolkij, Patinya Ma-ardlerd, Natthason Autthisin +4
This work considers the dynamics of the gauge vector and inflaton (dilaton) fields inspired by Kaluza-Klein theory in an inflationary universe with Bianchi type-I spacetime. The in…

A Thermodynamic Positivity Bound on Higher-Derivative 3-Form Couplings in de Sitter, and its Inflationary Consequences
Nutthaphat Lunrasri, Chakrit Pongkitivanichkul
We investigate the interplay between the thermodynamic positivity bounds and slow-roll inflation within a framework governed by a 3-form gauge field. Starting from classical consid…

A Kaluza-Klein Inspired Brans-Dicke Gravity with Dark Matter and Dark Energy Model
Chakrit Pongkitivanichkul, Daris Samart, Nakorn Thongyoi +1
We propose the Kaluza-Klein inspired Brans-Dicke gravity model containing possible existence of dark matter and dark energy. The massive scalar field coupled with gravity in 5 dime…
