Asymptotic structure of N = 2 $$ \mathcal{N}=2 $$ supergravity in 3D: extended super-BMS3 and nonlinear energy bounds
The asymptotically flat structure of $\mathcal{N}=(2,0)$ supergravity in three spacetime dimensions is explored. The asymptotic symmetries are spanned by an extension of the super-BMS$_3$ algebra, with two independent $\hat{u}(1)$ currents of electric and magnetic type. These currents are associated to $U(1)$ fields being even and odd under parity, respectively. Remarkably, …
