Gravitational waves in vector inflation
Alexey Golovnev, Viatcheslav Mukhanov, Vitaly Vanchurin
We discuss the gravitational waves (GW) in the context of vector inflation. We derive the action for tensor perturbations and find that tachyonic instabilities are present in most…
Vector Inflation
Alexey Golovnev, Viatcheslav Mukhanov, Vitaly Vanchurin
We propose a scenario where inflation is driven by non-minimally coupled massive vector fields. In an isotropic homogeneous universe these fields behave in presicely the same way a…
Cosmic string loops in the expanding universe
Ken D. Olum, Vitaly Vanchurin
We study the production of loops in the cosmic string network in the expanding background by means of a numerical simulation exact in the flat-spacetime limit and first-order in th…
