N $$ \mathcal{N} $$ -extended D = 4 supergravity, unconventional SUSY and graphene

open access: yesJournal of High Energy Physics, 2020
We derive a 2+1 dimensional model with unconventional supersymmetry at the boundary of an AdS4 N $$ \mathcal{N} $$ -extended supergravity, generalizing previous results. The (unconventional) extended supersymmetry of the boundary model is instrumental in
