Current Superalgebra and Non-unitary Conformal Field Theory
arXiv:hep-th/0212077 · doi:10.1016/j.physleta.2003.08.034
Abstract
Motivated by application of current superalgebras in the study of disordered systems such as the random XY and Dirac models, we investigate current superalgebra at general level . We construct its free field representation and corresponding Sugawara energy-momentum tensor in the non-standard basis. Three screen currents of the first kind are also presented.
