Non-metricity approach to Jackiw-Teitelboim gravity
Shin'ichi Nojiri, S. D. Odintsov
We construct 2d Jackiw-Teitelboim (JT) gravity in the framework of symmetric teleparallel gravity based on a non-metricity tensor. In symmetric teleparallel gravity, we often use t…
Wormhole solution free of ghosts in Einstein's gravity with two scalar fields
Shin'ichi Nojiri, G. G. L. Nashed
In this paper, we construct models that admit the traversable wormhole geometries in the framework of Einstein's gravity with two scalar fields. As well known, the energy condition…
U(1) Invariant F(R) Horava-Lifshitz Gravity
Josef Kluson, Shin'ichi Nojiri, Sergei D. Odintsov +1
This paper is devoted to the study of various aspects of projectable F(R) Horava-Lifshitz (HL) gravity. We show that some versions of F(R) HL gravity may have stable de Sitter solu…
