Frame invariant diffusive formulation of scalar-tensor gravity
Laur Järv, Sotirios Karamitsos
Thermodynamics provides a useful interpretation of scalar-tensor gravity, in which the effective imperfect fluid admitted by the nonminimal coupling features a temperature that is…
Friedmann cosmology with hyperfluids of constant equation of state
Ilaria Andrei, Damianos Iosifidis, Laur Järv +1
We discuss some aspects of cosmology in metric-affine theories of gravity where metric and affine connection are independent variables. Such constructions, apart from the usual ene…
The CosmoVerse White Paper: Addressing observational tensions in cosmology with systematics and fundamental physics
Eleonora Di Valentino, Jackson Levi Said, Adam Riess +533
The standard model of cosmology has provided a good phenomenological description of a wide range of observations both at astrophysical and cosmological scales for several decades.…
From inflation to dark energy in scalar-tensor cosmology
Jibitesh Dutta, Laur Jarv, Wompherdeiki Khyllep +1
The methods of dynamical systems have found wide applications in cosmology, with focus either upon inflation or upon the passage into dark energy era. In this paper, we endeavor to…
Cosmological dynamics of brane gravity: A global dynamical system perspective
Hmar Zonunmawia, Wompherdeiki Khyllep, Jibitesh Dutta +1
The braneworld model of gravity is well-known for several notable cosmological features such as self-acceleration originating from a geometric and not matter source, effective dark…
Nonmetricity formulation of general relativity and its scalar-tensor extension
Laur Järv, Mihkel Rünkla, Margus Saal +1
Einstein's celebrated theory of gravitation can be presented in three forms: general relativity, teleparallel gravity, and the rarely considered before symmetric teleparallel gravi…
