Coupled fermion–kink system in Jackiw–Rebbi model
Abstract In this paper, we study Jackiw–Rebbi model, in which a massless fermion is coupled to the kink of $$\lambda \phi ^4$$ λ ϕ 4 theory through a Yukawa interaction. In the original Jackiw–Rebbi model, the soliton is prescribed. However, we are interested in the back-reaction of the fermion on t...
