“…Since F vanishes for ζ → ∞, this D3 charge is concentrated at the bottom of the D5. This is also similar to the cigar case [40]. Notice that, for any value ζ 0 ≥ 0, the effective D3 charge is always the same.…”

We find non-critical string backgrounds in five and eight dimensions, holographically related to four-dimensional conformal field theories with N = 0 and N = 1 supersymmetries. In the five-dimensional case we find an AdS 5 background metric for a string model related to non-supersymmetric, conformal QCD with large number of colors and flavors and discuss the conjectured existence of a conformal window from the point of view of our solution. In the eight-dimensional string theory, we build a family of solutions of the form AdS 5 ×S 3 withS 3 a squashed three-sphere. For a special value of the ratio N f /N c , the background can be interpreted as the supersymmetric near-horizon limit of a system of color and flavor branes on R 1,3 times a known four-dimensional generalization of the cigar. The N = 1 dual theory with fundamental matter should have an IR fixed point only for a fixed ratio N f /N c . General features of the string/gauge theory correspondence for theories with fundamental flavors are also addressed.

The c = 1 Liouville theory has received some attention recently as the Euclidean version of an exact rolling tachyon background. In an earlier paper it was shown that the bulk theory can be identified with the interacting c = 1 limit of unitary minimal models. Here we extend the analysis of the c = 1-limit to the boundary problem. Most importantly, we show that the FZZT branes of Liouville theory give rise to a new 1-parameter family of boundary theories at c = 1. These models share many features with the boundary Sine-Gordon theory, in particular they possess an open string spectrum with band-gaps of finite width. We propose explicit formulas for the boundary 2-point function and for the bulk-boundary operator product expansion in the c = 1 boundary Liouville model. As a by-product of our analysis we also provide a nice geometric interpretation for ZZ branes and their relation with FZZT branes in the c = 1 theory. SPhT-T04/121hep-th/0409256 IHES/P/04/42

“…The Cardy constraint has been at the origin of many important insights concerning the operator content of a rational boundary CFT [74,77,79]. It has also been exploited for the investigation of some non-compact models [42,43,44,45,46]. The best way to analyze the annulus constraint is to introduce characters for the representations of the chiral algebra and study their modular transformations.…”

In this paper we study two classes of symmetric D-branes in the Nappi-Witten gravitational wave, namely D2 and S1 branes. We solve the sewing constraints and determine the bulk-boundary couplings and the boundary three-point couplings. For the D2 brane our solution gives the first explicit results for the structure constants of the twisted symmetric branes in a WZW model. We also compute the boundary four-point functions, providing examples of open string four-point amplitudes in a curved background. We finally discuss the annulus amplitudes, the relation with branes in AdS 3 and in S 3 and the analogy between the open string couplings in the H 4 model and the couplings for magnetized and intersecting branes.
