I Is there a relation between a soliton and a Goldstone boson?

[phoenix95]

I am currently reading this notes by t'Hooft, and I realized that a soliton and a Goldstone boson behave in a similar way: Both of them interpolate between the vacua. Keeping in mind Soliton is described classically in the notes(atleast until first few sections in chap1), Is there a relation between a soliton and a Goldstone boson?

I don't think so. With the sine-Gordon soliton in mind, it can be seen that the states to the right and left of a soliton are the same vacuum states, while a Goldstone boson separates different vacua.

I understand what you meant. moreover the fields that spawns these particle are completely different: Φ is the scalar field in symmetry breaking where as Goldstone bosons follow from broken symmetries. Thanks for the help.
