Abstract

In the framework of the Closed-Time-Path formalism, we show how topological defects may arise in Quantum Field Theory as result of a localized (inhomogeneous) condensation of particles. We demonstrate our approach on two examples; kinks in the 2Dλψ42D \lambda \psi^{4} theory (both at zero and finite temperature) and vortices in the complex 4Dλψ44D \lambda \psi^{4} theory.
