Higher-spin conserved currents in supersymmetric sigma models on symmetric spaces
J. M. Evans, C. A. S. Young
Local higher-spin conserved currents are constructed in the supersymmetric sigma models with target manifolds symmetric spaces . One class of currents is based on generators o…
Non-local charges and quantum integrability of sigma models on the symmetric spaces SO(2n)/SO(n)xSO(n) and Sp(2n)/Sp(n)xSp(n)
J. M. Evans, D. Kagan, C. A. S. Young
Non-local conserved charges in two-dimensional sigma models with target spaces and are shown to survive quantization, unspoi…
Commuting charges and symmetric spaces
J. M. Evans, A. J. Mountain
Every classical sigma-model with target space a compact symmetric space (with classical) is shown to possess infinitely many local, commuting, conserved charges which can…
Conserved charges and supersymmetry in principal chiral and WZW models
J. M. Evans, M. Hassan, N. J. MacKay +1
Conserved and commuting charges are investigated in both bosonic and supersymmetric classical chiral models, with and without Wess-Zumino terms. In the bosonic theories, there are…
Local conserved charges in principal chiral models
J. M. Evans, M. Hassan, N. J. MacKay +1
Local conserved charges in principal chiral models in 1+1 dimensions are investigated. There is a classically conserved local charge for each totally symmetric invariant tensor of…
The No-ghost Theorem for AdS_3 and the Stringy Exclusion Principle
J. M. Evans, M. R. Gaberdiel, M. J. Perry
A complete proof of the No-ghost Theorem for bosonic and fermionic string theories on AdS_3, or the group manifold of SU(1,1), is given. It is then shown that the restriction on th…
