A Consistent Calculation of Bubble-Nucleation Rates

We present a consistent picture of tunnelling in field theory. Our results apply both to high-temperature field theories in four dimensions and to zero-temperature threedimensional ones. Our approach is based on the notion of a coarse-grained potential Uk that incorporates the effect of fluctuations with characteristic momenta above a given scale k. Uk is non-convex and becomes equal to the con...

A consistent approach to bubble-nucleation theory

We summarize recent work on the consistent calculation of bubble-nucleation rates. Our approach is based on the notion of a real coarse-grained potential. The bubble-nucleation rate is calculated through an expansion around the semiclassical saddle point associated with tunnelling. We resolve outstanding problems related to the convexity of the potential, the double-counting of the effect of fl...

A cosmic microwave background feature consistent with a cosmic texture.

The Cosmic Microwave Background provides our most ancient image of the universe and our best tool for studying its early evolution. Theories of high-energy physics predict the formation of various types of topological defects in the very early universe, including cosmic texture, which would generate hot and cold spots in the Cosmic Microwave Background. We show through a Bayesian statistical an...

Constraining cosmic microwave background consistent primordial voids with cluster evolution

Using cosmological simulations, we make predictions for the distribution of clusters in a plausible non-Gaussian model where primordial voids nucleated during inflation act together with scale-invariant adiabatic Gaussian fluctuations as seeds for the formation of large-scale structure. The parameters of the void network are constrained by the cosmic microwave background (CMB) fluctuations and ...

Time dependent cosmic–ray shock acceleration with self–consistent injection

One of the key questions to understanding the efficiency of diffusive shock acceleration of the cosmic rays (CRs) is the injection process from thermal particles. A self–consistent injection model based on the interactions of the suprathermal particles with self–generated magneto–hydrodynamic waves has been developed recently by Malkov (1998). By adopting this analytic solution, a numerical tre...
