Correlators in Timelike Bulk Liouville Theory
نویسندگان
چکیده
Liouville theory with a negative norm boson and no screening charge corresponds to an exact classical solution of closed bosonic string theory describing time-dependent bulk tachyon condensation. A simple expression for the two point function is proposed based on renormalization/analytic continuation of the known results for the ordinary (positive-norm) Liouville theory. The expression agrees exactly with the minisuperspace result for the closed string pair-production rate (which diverges at finite time). Puzzles concerning the three-point function are presented and discussed. e-print archive: http://lanl.arXiv.org/abs/hep-th/0303221 370 Correlators in Timelike Bulk Liouville Theory

Energy Quantisation in Bulk Bouncing Tachyon
We argue that the closed string energy in the bulk bouncing tachyon background is to be quantised in a simple manner as if strings were trapped in a finite time interval. We discuss it from three different viewpoints; (1) the timelike continuation of the sinhGordon model, (2) the dual matrix model description of the (1+ 1)-dimensional string theory with the bulk bouncing tachyon condensate, (3)...
متن کاملBulk correlation functions in 2 D quantum gravity 1
We compute bulk 3-and 4-point tachyon correlators in the 2d Liouville gravity with non-rational matter central charge c < 1, following and comparing two approaches. The continuous CFT approach exploits the action on the tachyons of the ground ring generators deformed by Liouville and matter " screening charges ". A by-product general formula for the matter 3-point OPE structure constants is der...
متن کاملLiouville D-branes in Two-Dimensional Strings and Open String Field Theory
We study open strings in the noncritical c = 1 bosonic string theory compactified on a circle at self-dual radius. These strings live on D-branes that are extended along the Liouville direction (FZZT branes). We present explicit expressions for the disc twoand three-point functions of boundary operators in this theory, as well as the bulk-boundary two-point function. The expressions obtained ar...
متن کاملD–Branes in N=2 Liouville Theory and its Mirror
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 ...
متن کاملBTZ black hole and quantum Hall effect in the bulk/boundary dynamics
We point out the close relationship between the BTZ black hole and QHE (Quantum Hall effect) in the (2+1)-dimensional bulk/boundary theory. It is shown that the Chern-Simons/Liouville(Chern-Simons/chiral boson) are an effective description for the BTZ black hole (QHE). Also the IR(bulk)UV(boundary) connection for a black hole information bound is realized as the UV(low-lying excitations on bulk...
