Inflationary models that generalize the constant roll constraint
B. Boisseau, H. Giacomini
Recently a class of inflationary models satisfying the constant rate of roll constraint, , has been studied and compared with the latest cosmological observat…
Bouncing Universes in Scalar-Tensor Gravity Around Conformal Invariance
B. Boisseau, H. Giacomini, D. Polarski
We consider the possibility to produce a bouncing universe in the framework of scalar-tensor gravity when the scalar field has a nonconformal coupling to the Ricci scalar. We prove…
Scalar Field Cosmologies With Inverted Potentials
B. Boisseau, H. Giacomini, D. Polarski
Regular bouncing solutions in the framework of a scalar-tensor gravity model were found in a recent work. We reconsider the problem in the Einstein frame (EF) in the present work.…
Bouncing Universes in Scalar-Tensor Gravity Models admitting Negative Potentials
B. Boisseau, H. Giacomini, D. Polarski +1
We consider the possibility to produce a bouncing universe in the framework of scalar-tensor gravity models in which the scalar field potential may be negative, and even unbounded…
Electrostatics in a simple wormhole revisited
Bruno Boisseau, Bernard Linet
The electrostatic potential generated by a point charge at rest in a simple static, spherically symmetric wormhole is given in the form of series of multipoles and in closed form.…
Exact cosmological solution of a Scalar-Tensor Gravity theory compatible with the model
B. Boisseau
We consider the massive scalar-tensor theory in the Jordan frame and , where corresponds to a constant Brans-Dicke parameter $ω_{BD}=1/…
