Superconformal index for $$ \mathcal{N} $$ = 4 super Yang-Mills and elliptic Macdonald polynomials

A bstract We establish a connection between the superconformal index of $$ \mathcal{N} $$ N = 4 U ( N ) SYM and the elliptic Ruijsenaars-Schneider integrable system. The index admits an expression in terms of elliptic Macdonald polynomials, which leads to a compact summation over...
