Spontaneous symmetry breaking in 2D supersphere sigma models and applications to intersecting loop soups

Etienne Granet, Jesper Lykke Jacobsen, Hubert Saleur

Two-dimensional sigma models on superspheres $S^{r-1|2s}\cong OSp(r|2s)/OSp(r-1|2s)$ are known to flow to weak coupling $g_{\sigma }\to 0$ in the IR when $r-2s<2$. Their long-dista…
