Query: Drinfeld Basis And a Nonclassical Free Boson Representation of Twisted
  Quantum Affine Superalgebra $U_q[osp(2|2)^{(2)}]$}   We derive from the super RS algebra the Drinfeld basis of the twisted quantum
affine superalgebra $U_q[osp(2|2)^{(2)}]$ by means of the Gauss decomposition
technique. We explicitly construct a nonclassical level-one representation of
$U_q[osp(2|2)^{(2)}]$ in terms of two $q$-deformed free boson fields.
