Defect Formation Through Boson Condensation in Quantum Field Theory

TL;DR

This paper reviews how topological defects like kinks, vortices, and monopoles emerge from boson condensation in quantum field theory, discussing formalism, symmetry breaking, and finite temperature effects.

Contribution

It provides a comprehensive review of the QFT formalism for defect formation via boson condensation, including symmetry breaking and thermal effects.

Findings

Topological defects are described as non-homogeneous boson condensates.

Finite temperature influences defect formation and phase transitions.

The formalism connects defects with spontaneous symmetry breaking mechanisms.

Abstract

Kinks, vortices, monopoles are extended objects, or defects, of quantum origin with topologically non-trivial properties and macroscopic behavior. They are described in Quantum Field Theory in terms of non-homogeneous boson condensation. I will review the related QFT formalism, the spontaneous breakdown of symmetry framework in which the defects appear and discuss finite temperature effects, also in connection with phase transition problematics.
