String-wall composites winding around a torus knot vacuum in an axionlike model

Minoru Eto, Takashi Hiramatsu, Izumi Saito +1

We study a simple axionlike model with a charged scalar $\varphi$ and a double-charged scalar $\zeta$ of global $U(1)$ symmetry. A particular feature of our model is that a vacuum manifold i…
