Primary Fields and Screening Currents of gl(2|2) Non-unitary Conformal Field Theory
نویسندگان
چکیده
The non-semisimple gl(2|2)k current superalgebra in the standard basis and the corresponding non-unitary conformal field theory are investigated. Infinite families of primary fields corresponding to all finite-dimensional irreducible typical and atypical representations of gl(2|2) and three (two even and one odd) screening currents of the first kind are constructed explicitly in terms of ten free fields. PACS: 11.25Hf.

Current Superalgebra and Non - unitary Conformal Field Theory
Motivated by application of current superalgebras in the study of disordered systems such as the random XY and Dirac models, we investigate gl(2|2) current superalgebra at general level k. 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.
متن کاملCoherent State Construction of Representations of osp(2|2) and Primary Fields of osp(2|2) Conformal Field Theory
Representations of the superalgebra osp(2|2) and current superalgebra osp(2|2) (1) k in the standard basis are investigated. All finite-dimensional typical and atypical representations of osp(2|2) are constructed by the vector coherent state method. Primary fields of the non-unitary conformal field theory associated with osp(2|2) (1) k in the standard basis are obtained for arbitrary level k.
متن کاملTopological Correlation Functions in Minkowski Spacetime
We consider a class of non-unitary Toda theories based on the Lie superalgebras A(1)(n, n) in two-dimensional Minkowski spacetime, which can be twisted into a topological sector. In particular we study the simplest example with n = 1 and real fields, and show how this theory can be treated as an integrable perturbation of the A(1, 0) superconformal model. We construct the conserved currents and...
متن کاملA Unified Conformal Field Theory Description of Paired Quantum Hall States
The wave functions of the Haldane-Rezayi paired Hall state have been previously described by a non-unitary conformal field theory with central charge c = −2. Moreover, a relation with the c = 1 unitary Weyl fermion has been suggested. We construct the complete unitary theory and show that it consistently describes the edge excitations of the Haldane-Rezayi state. Actually, we show that the unit...
متن کاملCorrelation Functions of (2k−1, 2) Minimal Matter Coupled to 2D Quantum Gravity
We compute N -point correlation functions of non-unitary (2k−1, 2) minimal matter coupled to 2D quantum gravity on a sphere using the continuum Liouville field approach. A gravitational dressing of the matter primary field with the minimum conformal weight is used as the cosmological operator. Our results are in agreement with the correlation functions of the one-matrix model at the k-th critic...
