  Recently, Maulik and Okounkov proposed an integrable lattice model where the
degree of freedom at each site is identical to the Hilbert space of free boson
in two dimensions. We give a brief review of their construction and explain the
relation with $\mathcal{W}_n$ algebra and Calogero-Sutherland model. As a
generalization, we examine the Yangian associated with $\mathcal{N}=1$
superconformal algebra which describes a supersymmetric extension of
Calogero-Sutherland model and compare it with the literature.
