Comments on D-branes in Kazama-Suzuki models and Landau-Ginzburg theories
We study D-branes in Kazama-Suzuki models by means of the boundary state description. We can identify the boundary states of Kazama-Suzuki models with the solitons in N = 2 Landau-Ginzburg theories. We also propose a geometrical interpretation of the boundary states in Kazama-Suzuki models.
متن کاملTwisted boundary states in Kazama-Suzuki models
We construct Cardy states in the Kazama-Suzuki model G/H × U(1), which satisfy the boundary condition twisted by the automorphisms of the coset theory. We classify all the automorphisms of G/H × U(1) induced from those of the G theory. The automorphism group contains at least a Z2 as a subgroup corresponding to the charge conjugation. We show that in several models there exist extra elements ot...
متن کاملGrassmannian Topological Kazama-Suzuki Models and Cohomology
We investigate in detail the topological gauged Wess-Zumino-Witten models describing topological Kazama-Suzuki models based on complex Grassmannians. We show that there is a topological sector in which the ring of observables (constructed from the Grassmann odd scalars of the theory) coincides with the classical cohomology ring of the Grassmannian for all values of the level k. We perform a det...
متن کاملMirror symmetry for the Kazama-Suzuki models
We study the N = 2 coset models in their formulation as supersymmetric gauged Wess-Zumino-Witten models. A model based on the coset G/H is invariant under a symmetry group isomorphic to ZZk+Q, where k is the level of the model and Q is the dual Address after September 1, 1994: Department of Physics, Yale University, New Haven, CT 06511 Coxeter number of G. Using a duality-like relationship, we ...
متن کاملThe large level limit of Kazama - Suzuki models
superconformal Wn+1 minimal models that appear in the context of the supersymmetric higher-spin AdS3/CFT2 duality. These models are constructed as Kazama-Suzuki coset models of the form SU(n+1)/U(n). We determine a family of boundary conditions in the limit theories, and use the modular bootstrap to obtain the full bulk spectrum of N = 2 super-Wn+1 primaries in the theory. We also confirm the i...
