Superstring sigma models from spin chains: the SU(1,1|1) case
We derive the coherent state representation of the integrable spin chain Hamiltonian with non-compact supersymmetry group $G=$SU$(1,1|1)$. By passing to the continuous limit, we find a spin chain sigma model describing a string moving on the supercoset $G/H$, $H$ being the stabilizer group. The acti...
