Non-Gaussianity of the distribution tails in CMB
Vitaly Vanchurin
We analyze statistical properties of the separate multipole moments of the CMB temperature maps and find that the distribution tails are slightly non-Gaussian. Moreover, the deviat…
Cosmological perturbations from vector inflation
Alexey Golovnev, Vitaly Vanchurin
We analyze the behavior of linear perturbations in vector inflation. In contrast to the scalar field inflation, the linearized theory with vector fields contains couplings between…
Stationary Measure in the Multiverse
Andrei Linde, Vitaly Vanchurin, Sergei Winitzki
We study the recently proposed "stationary measure" in the context of the string landscape scenario. We show that it suffers neither from the "Boltzmann brain" problem nor from the…
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…
