D–Branes in N=2 Liouville Theory and its Mirror
نویسندگان
چکیده
We study D-branes in the mirror pair N = 2 Liouville/supersymmetric SL(2,R)/U(1) coset superconformal field theories. We build D0, D1 and D2 branes, on the basis of the boundary state construction for the H 3 conformal field theory. We also construct D0-branes in an orbifold that rotates the angular direction of the cigar. We show how the poles of correlators associated to localized states and bulk interactions naturally decouple in the one-point functions of localized and extended branes. We stress the role played in the analysis of D-brane spectra by primaries in SL(2,R)/U(1) which are descendents of the parent theory. ∗Unité mixte du CNRS et de l’Ecole Normale Supérieure, UMR 8549.

Orientifolds in N = 2 Liouville Theory and its Mirror
We consider unoriented strings in the supersymmetric SL(2,R)/U(1) coset, which describes the two-dimensional Euclidean black hole, and its mirror dual N = 2 Liouville theory. We analyze the orientifolds of these theories from several complementary points of view: the parity symmetries of the worldsheet actions, descent from known AdS3 parities, and the modular bootstrap method (in some cases we...
متن کاملD - branes in Singular Calabi - Yau n - fold and N = 2 Liouville Theory Tohru Eguchi and Yuji Sugawara
Making use of the N = 2 Liouville theory and world-sheet techniques, we study the properties of D-branes wrapped around vanishing SUSY cycles of singular Calabi-Yau n-folds (n = 2, 3, 4). After constructing boundary states describing the wrapped branes, we evaluate the disc amplitudes corresponding to the periods of SUSY cycles. We use the old technique of KPZ scaling in Liouville theory and de...

متن کاملModular Bootstrap for Boundary N = 2 Liouville Theory
We study the boundary N = 2 Liouville theory based on the “modular bootstrap” approach. As fundamental conformal blocks we introduce the “extended characters” that are defined as the proper sums over spectral flows of irreducible characters of the N = 2 superconformal algebra (SCA) and clarify their modular transformation properties in models with rational central charges. We then try to classi...
متن کاملModular Bootstrap of Boundary N = 2 Liouville Theory *
We present our recent studies on the dynamics of boundary N = 2 Liouville theory. We use the representation theory of N = 2 superconformal algebra and the method of modular bootstrap to derive three classes of boundary states of the N = 2 Liouville theory. Class 1 and 2 branes are analogues of ZZ and FZZT branes of N = 0, 1 Liouville theory while class 3 branes come from U(1) degrees of freedom...
