Conventionalism, cosmology and teleparallel gravity

Laur Järv, Piret Kuusk

We consider homogeneous and isotropic cosmological models in the framework of three geometrical theories of gravitation: in the Einstein general relativity they are given in terms…

Constraints on non-Newtonian gravity and axionlike particles from measuring the Casimir force in nanometer separation range

G. L. Klimchitskaya, P. Kuusk, V. M. Mostepanenko

We obtain constraints on the Yukawa-type corrections to Newton's gravitational law and on the coupling constant of axionlike particles to nucleons following from the experiment on…

Post-Newtonian parameter for multiscalar-tensor gravity with a general potential

Manuel Hohmann, Laur Jarv, Piret Kuusk +2

We compute the parametrized post-Newtonian parameter in the case of a static point source for multiscalar-tensor gravity with completely general nonderivative couplings and pot…

Invariant slow-roll parameters in scalar-tensor theories

Piret Kuusk, Mihkel Rünkla, Margus Saal +1

A general scalar-tensor theory can be formulated in different parametrizations that are related by a conformal rescaling of the metric and a scalar field redefinition. We compare f…

The formalism of invariants in scalar-tensor and multiscalar-tensor theories of gravitation

Laur Jarv, Piret Kuusk, Margus Saal +1

We give a brief summary of the formalism of invariants in general scalar-tensor and multiscalar-tensor gravities without derivative couplings. By rescaling of the metric and repara…

Invariant quantities in the multiscalar-tensor theories of gravitation

Piret Kuusk, Laur Jarv, Ott Vilson

The aim of the current paper is to study the multiscalar-tensor theories of gravity without derivative couplings. We construct a few basic objects that are invariant under a Weyl r…
