Correlation functions in scalar field theory at large charge
Abstract We compute general higher-point functions in the sector of large charge operators ϕ n , ϕ ¯ n $$ {\overline{\phi}}^n $$ at large charge in O(2) ϕ ¯ ϕ 2 $$ {\left(\overline{\phi}\phi \right)}^2 $$ theory. We find that there is a special class of “extremal” correlators having only one inserti...
