Instability of the ACW model, and problems with massive vectors during inflation
Burak Himmetoglu, Carlo R. Contaldi, Marco Peloso
We prove that the anisotropic inflationary background of the Ackerman-Carroll-Wise model, characterized by a fixed-norm vector field, is unstable. We found the instability by expli…

Instability of anisotropic cosmological solutions supported by vector fields
Burak Himmetoglu, Carlo R. Contaldi, Marco Peloso
Models with vector fields acquiring a non-vanishing vacuum expectation value along one spatial direction have been proposed to sustain a prolonged stage of anisotropic accelerated…
