AdS Carroll Chern-Simons supergravity in 2+1 dimensions and its flat limit

Understand

Carroll symmetries arise when the velocity of light is sent to zero (ultra-relativistic limit).

• In this paper, we present the construction of the three-dimensional Chern-Simons supergravity theory invariant under the so-called AdS Carroll superalgebra, which was obtained in the literature as a contraction of the AdS superalgebra.
• The action is characterized by two coupling constants.
• Subsequently, we study its flat limit, obtaining the three-dimensional Chern-Simons supergravity theory invariant under the super-Carroll algebra, which is a contraction of the Poincar\'e superalgebra.
