Johnson<br/>Building on earlier work, we develop an equation-of-motion method for calculating magnetic seed fields generated from currents arising from charged W^{±} fields in bubble collisions during a first-order primordial electroweak phase transition allowed in some proposed extensions of the standard mode...<br/>[Phys.

Joukovskaya, and S. Yu. Vernov<br/>The stability of isotropic cosmological solutions in the Bianchi I model is considered. We prove that the stability of isotropic solutions in the Bianchi I metric for a positive Hubble parameter follows from their stability in the Friedmann-Robertson-Walker metric. This result is applied to models...<br/>[Phys. Rev. D 80, 083532] Published Thu Oct 29, 2009 I. Ya. Aref’eva, N. V. Bulatov, L. V. Joukovskaya, and S. Yu.
