Abstract:

In this note, we research the Abelian Higgs model subject to the Born-Infeld theory for which the BPS equations can be reduced to a quasi-linear differential equation. We show that the equation exists a unique solution under two interesting boundary conditions which realize the corresponding phase transition. The solution is constructed using a dynamical shooting method for which the correct shooting slope is unique. We also obtain the sharp asymptotic estimate for the solution at infinity.

Key words: Born-Infeld theory, Abelian Higgs model, domain wall, dynamical shooting method, existence and uniqueness, asymptotic estimates
