GARCIA, J. L; MELFO, A e PANTOJA, N. Formación de paredes de dominio en transiciones de fase de primer orden. Rev. mex. fis. [online]. 2006, vol.52, suppl.3, pp.123-126. ISSN 0035-001X.
We study formation of domain wall in first order phase transition triggered by a scalar field that breaks spontaneously a Z2 symemetry. An algorithm that allows simulation of bubble nucleation and collision, and counting of open and closed walls formed, is implemented. The case of an approximate Z2 symetry, relevant to recent proposals of solutions to the domain wall problem in cosmology is considered.
