Generalized symmetries in singularity-free nonlinear $\ddot{I}ƒ$ models and their disordered phases

Salvatore D. Pace, Chenchang Zhu, Agnès Beaudry +1

We study the nonlinear $\ddot{I}ƒ$-model in $(d+1)$-dimensional spacetime with connected target space $K$ and show that, at energy scales below singular field configurations (such as vo…
