Scalar-tensor cosmologies: fixed points of the Jordan frame scalar field
Laur Jarv, Piret Kuusk, Margus Saal
We study the evolution of homogeneous and isotropic, flat cosmological models within the general scalar-tensor theory of gravity with arbitrary coupling function and potential. Aft…
Geodesic multiplication as a tool for classical and quantum gravity
Piret Kuusk, Eugen Paal
Algebraic systems called the local geodesic loops and their tangent Akivis algebras are considered. Their possible role in theory of gravity is considered. Quantum conditions for t…
Scalar-tensor cosmology at the general relativity limit: Jordan vs Einstein frame
Laur Jarv, Piret Kuusk, Margus Saal
We consider the correspondence between the Jordan frame and the Einstein frame descriptions of scalar-tensor theory of gravitation. We argue that since the redefinition of the scal…
Measurement of time in nonrelativistic quantum and classical mechanics
Piret Kuusk, Madis Koiv
Possible theoretical frameworks for measurement of (arrival) time in the nonrelativistic quantum mechanics are reviewed. It is argued that the ambiguity between indirect measuremen…
Geodesic multiplication and quantum kinematics in a Newtonian spacetime
Piret Kuusk
We consider a quantum test particle in the background of a Newtonian gravitational field in the framework of Cartan's formulation of nonrelativistic spacetimes. We have proposed a…
