In hot pursuit of a stable wormhole in beyond Horndeski theory

S. Mironov, V. Rubakov, V. Volkova

We consider the issue of stability at the linearized level for static, spherically symmetric wormhole solutions within a subclass of scalar-tensor theories of beyond Horndeski type…

Genesis with general relativity asymptotics in beyond Horndeski theory

S. Mironov, V. Rubakov, V. Volkova

We suggest a novel version of a cosmological Genesis model within beyond Horndeski theory. It combines the initial Genesis behavior of Creminelli et al. [arXiv:1007.0027, arXiv:120…

Towards wormhole beyond Horndeski

S. Mironov, V. Rubakov, V. Volkova

We address the issue of whether a no-go theorem for static, spherically symmetric wormholes, proven in Horndeski theories, can be circumvented by going beyond Horndeski. We show th…

On the stability of self-accelerating Universe in modified gravity with dynamical torsion

V. Nikiforova

We consider the model of modified gravity with dynamical torsion. This model was previously found to have promising stability properties about various backgrounds. Here we study th…

Perturbations on and off de Sitter brane in anti-de Sitter bulk

M. Libanov, V. Rubakov

Motivated by holographic models of (pseudo)conformal Universe, we carry out complete analysis of linearized metric perturbations in the time-dependent two-brane setup of the Lykken…

Self-accelerating Universe in modified gravity with dynamical torsion

V. Nikiforova, S. Randjbar-Daemi, V. Rubakov

We consider a model belonging to the class of gravities with dynamical torsion. The model is free of ghosts and gradient instabilities about Minkowski and torsionless Einstein back…
