Supersymmetric WZW models and twisted K theory of SO(3)

We present an encompassing treatment of D-brane charges in supersymmetric SO(3) WZW models. There are two distinct supersymmetric CFTs at each even level: the standard bosonic SO(3) modular invariant…

Closed string tachyons in a smooth curved background

Closed string tachyon condensation has been studied in orbifolds C^2/Z_{N,p} of flat space, using the chiral ring of the underlying N=2 conformal field theory. Here we show that similar phenomena…

The SU(2) WZW model at large level N can be interpreted semiclassically as string theory on S3 with N units of Neveu-Schwarz H-flux. While globally geometric, the model nevertheless exhibits an…

We reconsider the role that bundle gerbes play in the formulation of the WZW model on closed and open surfaces. In particular, we show how an analysis of bundle gerbes on groups covered by SU(N)…

We analyze the chiral properties of (orbifold) conformal field theories which are obtained from a given conformal field theory by modding out by a finite symmetry group. For a class of orbifolds, we…

The operator algebra and twisted KZ equations of WZW orbifolds

We obtain the operator algebra of each twisted sector of all WZW orbifolds, including the general twisted current algebra and the algebra of the twisted currents with the twisted affine primary…
