Non-minimally Sample Clauses

Non-minimally enhanced scalar model‌ Unlike the geometric scalar model considered above, the non-minimally enhanced scalar model (NES) from [85], takes a scalar field from the matter sector and introduces a non- minimal coupling rather than extracting a degree of freedom from the gravity sector. The coupling functions are given by ωR = 1 + ξψ2, ωψ = 1 and ωφ = 0. The strength of the quadratic non-minimal coupling is determined by the constant ξ. The deformed effective Lagrangian for this model is given by, LNES = √ { ( q |β| 1 + ξψ2 ) (R − K) + 1 ν2 ψ a ( ) − ∂aψ∂ ψ (− 2 β 2 β 2ξ ψνψ v + ψ∆ψ + ∂ 2β a ψ∂aψ)} − √q U (ψ) .
