Teleparallel quintessence with a nonminimal coupling to a boundary term

We propose a new model in the teleparallel framework where we consider a scalar field nonminimally coupled to both the torsion T and a boundary term given by the divergence of the torsion vector B 1⁄4 2e ∂μðeTμÞ. This is inspired by the relation R 1⁄4 −T þ B between the Ricci scalar of general relativity and the torsion of teleparallel gravity. This theory in suitable limits incorporates both t...

Inflation and quintessence with nonminimal coupling

The nonminimal coupling (NMC) of the scalar field to the Ricci curvature is unavoidable in many cosmological scenarios. Inflation and quintessence models based on nonminimally coupled scalar fields are studied, with particular attention to the balance between the scalar potential and the NMC term ξRφ2/2 in the action. NMC makes acceleration of the universe harder to achieve for the usual potent...

Reply to Comment on “Nonuniqueness of algebraic first-order density-matrix functionals”[Phys. Rev. A 92, 012520 (2015)]

It is shown that symmetry considerations do not alter the conclusions of the original paper, that there exists an example of an electronic system for which at several geometries the one-matrix eigenvalues are identical, but the two-matrix spectrum is not. It is still therefore the case that JK and related functionals that depend on the one-matrix eigenvalues to model the two-matrix can not be m...

Open inflation from quantum cosmology with a strong nonminimal coupling

We propose the mechanism of quantum creation of the open Universe in the observable range of values of Ω. This mechanism is based on the no-boundary quantum state with the Hawking-Turok instanton applied to the model with a strong nonminimal coupling of the inflaton field. We develop the slow roll perturbation expansion for the instanton solution and obtain a nontrivial contribution to the clas...
