Extended multi-scalar field theories in $$(1+1)$$ ( 1 + 1 ) dimensions
Abstract We present the explicit construction of some multi-scalar field theories in $$(1+1$$ ( 1 + 1 ) dimensions supporting BPS (Bogomol’nyi–Prasad–Sommerfield) kink solutions. The construction is based on the ideas of the so-called extension method. In particular, several new interesting two-scal...
