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, MarÃa José Guzmán +1
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…
