Minimal representations of the metaplectic Lie supergroup and the super Segal-Bargmann transform

Abstract: We construct a Schr\"odinger model and a Fock model of a minimal representation of the metaplectic Lie supergroup $\mathrm{Mp}(2m|2n,2n)$. Then, we show that the Schr\"odinger model of the minimal representation leads to an already known Schr\"odinger model of the metaplectic representation of $\mathrm{Mp}(2m|2n,2n)$. Therefore, the Fock model of the minimal representation allows us to construct a Fock model of this metaplectic representation. We then construct an intertwining super Segal-Bargmann transform which extends the classical Segal-Bargmann transform.
