Bianchi IX dynamics with a phantom field
Adel Awad, Dmitry Chirkov, Alexey Golovnev +1
We consider Bianchi IX dynamics of a Universe filled with a massless phantom field. Such an exotic matter source enables regimes impossible in vacuum or with a standard scalar fiel…
Primary Constraints of Newer General Relativity
Carmen Ferrara, Alexey Golovnev, María José Guzmán
We study the primary constraint structure of Newer General Relativity, a gravity theory based on a torsionless teleparallel geometry. The gravitational action is built from a scala…
More on Bianchi I spacetimes and f(T) gravity
Alexey Golovnev, Mustafa M. Hemida
Bianchi I cosmological solutions in f(T) gravity are discussed. We start from diagonal metrics and tetrads and show that their dynamical equations are pretty much tractable analyti…
Weak Gravity Limit in Newer General Relativity
Alexey Golovnev, Sofia Klimova, A. N. Semenova +1
We analyse linearised field equations around the Minkowski metric with its standard flat parallel transport in models of Newer GR, that is quadratic actions in terms of nonmetricit…
Conformal Transformations and Cosmological Perturbations in New General Relativity
Alexey Golovnev, A. N. Semenova, V. P. Vandeev
We study conformal transformations in the most general parity-preserving models of the New General Relativity type. Then we apply them to analysis of cosmological perturbations in…
Gravitational Waves in New General Relativity
Alexey Golovnev, A. N. Semenova, V. P. Vandeev
The models of New General Relativity have recently got attention of research community, and there are some works studying their dynamical properties. The formal aspects of this inv…
