  • A bstractWe present an approach to evaluate the full operatorial Q-system of all up,q|r+s$$ \mathfrak{u}\left(p,q\Big|r+s\right) $$-invariant spin chains with representations of Jordan-Schwinger type. In particular, this includes the super spin chain of planar N=4$$ \mathcal{N}=4 $$ super Yang-Mills theory at one loop in the presence of a diagonal twist. Our method is based on the oscillator construction of Q-operators. The Q-operators are built as traces over Lax operators which are degenerate… CONTINUE READING
