Semi-analytic techniques for calculating bubble wall profiles

29 Jul 2016  ·  Akula Sujeet, Balázs Csaba, White Graham A. ·

We present semi-analytic techniques for finding bubble wall profiles during first order phase transitions with multiple scalar fields. Our method involves reducing the problem to an equation with a single field, finding an analytic solution and perturbing around it... The perturbations can be written in a semi-analytic form. We argue that our technique lacks convergence problems and demonstrate the speed of convergence on an example potential. read more
