Cosmic string loops: large and small, but not tiny
Vitaly Vanchurin
We develop an analytical model to study the production spectrum of loops in the cosmic string network. In the scaling regime, we find two different scales corresponding to large (o…
Attractor scenarios and superluminal signals in k-essence cosmology
Jin U Kang, Vitaly Vanchurin, Sergei Winitzki
Cosmological scenarios with k-essence are invoked in order to explain the observed late-time acceleration of the universe. These scenarios avoid the need for fine-tuned initial con…
Geodesic measures of the landscape
Vitaly Vanchurin
We study the landscape models of eternal inflation with an arbitrary number of different vacua states, both recyclable and terminal. We calculate the abundances of bubbles followin…
Numerical search for a fundamental theory
Vitaly Vanchurin
We propose a numerical test of fundamental physics based on the complexity measure of a general set of functions, which is directly related to the Kolmogorov (or algorithmic) compl…
