Quantum SUSY Algebra of $Q$-lumps in the Massive Grassmannian Sigma Model

Hiroaki Nakajima, Phillial Oh, Sunyoung Shin

We compute the $\mathcal{N}=2$ SUSY algebra of the massive Grassmannian sigma model in 2+1 dimensions. We first rederive the action of the model by using the Scherk-Schwarz dimensi…
