Comments on D-branes in Kazama-Suzuki models and Landau-Ginzburg theories
Masatoshi Nozaki
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-Gi…
Formation of Spherical D2-brane from Multiple D0-branes
Yasuaki Hikida, Masatoshi Nozaki, Yuji Sugawara
We study D-branes in SU(2) WZW model by means of the boundary state techniques. We realize the ``fuzzy sphere'' configuration of multiple D0-branes as the boundary state with the i…
Singular Calabi-Yau Manifolds and ADE Classification of CFTs
Michihiro Naka, Masatoshi Nozaki
We study superstring propagations on the Calabi-Yau manifold which develops an isolated ADE singularity. This theory has been conjectured to have a holographic dual description in…
Tachyon Condensation on Fuzzy Sphere and Noncommutative Solitons
Yasuaki Hikida, Masatoshi Nozaki, Tadashi Takayanagi
We study a brane-antibrane system and a non-BPS D-brane in SU(2) WZW model. We first discuss the tachyon condensation using the vertex operator formalism and find the generation of…
Boundary states in Gepner models
Michihiro Naka, Masatoshi Nozaki
We extend the construction of the boundary states in Gepner models to the non-diagonal modular invariant theories, and derive the same supersymmetric conditions as the diagonal the…
