Evolution of Information and Complexity in an Ever-Expanding Universe
Using the usual definitions of information and entropy in quantum gravity and statistical mechanics and the existing views about the relation between information and complexity, we examine the evolution of complexity in an ever expanding universe.

متن کاملPerturbative nonequilibrium dynamics of phase transitions in an expanding universe
It has long been apparent that the hot, dense matter present in the early universe might undergo a variety of phase transitions [1]. In particular, the “new inflation” scenario of Linde [2] and Albrecht and Steinhardt [3] (modifying an earlier proposal of Guth [4]) suggests that a symmetry-breaking phase transition at the GUT scale would lead to a period of quasi-exponential expansion, perhaps ...
