Defects and Wilson Loops in 3d QFT from D-branes in AdS4 × CP
نویسندگان
چکیده
We study the Wilson loops and defects in the three dimensional QFT from the D-branes in the AdS4× CP3 geometry. We find out explicit D-brane configurations in the bulk which correspond to both straight and circular Wilson lines extended to the boundary of AdS4. We analyze critically the role of boundary contributions to the D2-branes with various topology and to the fundamental string actions.

Wilson Loops in 3 d QFT from D - branes in AdS 4 × CP 3
We study the Wilson loops in the three dimensional QFT from the D-branes in the AdS4× CP3 geometry. We find out explicit D-brane configurations in the bulk which correspond to both straight and circular Wilson lines extended to the boundary of AdS4. We analyze critically the role of boundary contributions to the D2-branes with various topology and fundamental string actions.
متن کاملWilson Loops from D - branes in AdS 4 × CP 3 with B NS
We study Wilson loops in N=6 superconformal Chern-Simons theory with gauge group U(M)× U(N) that is dual to N M2-branes and (M-N) fractional M2-branes, equivalently, discrete 3-form holonomy at C4/Zk orbifold singularity. We give description of these Wilson loops in terms of macroscopic fundamental string and D6-branes in the dual AdS4× CP3 geometry with NS-NS B field turned on over CP1 ⊂ CP3.
متن کاملWilson loops in 3 - dimensional N = 6 supersymmetric Chern - Simons Theory and their string theory duals
We study Wilson loops in the three-dimensional N = 6 supersymmetric Chern-Simons theory recently constructed by Aharony, Bergman, Jafferis and Maldacena, that is conjectured to be dual to type IIA string theory on AdS4×CP. We construct loop operators in the Chern-Simons theory which preserve 1/6 of the supercharges and calculate their expectation value up to 2-loop order at weak coupling. The e...
متن کاملsuperspace for the type IIA superstring and D-branes
We lift the bosonic AdS4 × CP 3 solution of type IIA supergravity preserving 24 supersymmetries to a D = 10 superspace which has 32 Grassmann–odd directions. The type IIA superspace is obtained from D = 11 via dimensional reduction of the coset superspace OSp(8|4)/SO(7) × SO(1, 3) by realizing the latter as a Hopf fibration over the former. This construction generalizes to superspace the Hopf f...
متن کاملABJM Dibaryon Spectroscopy
We extend the proposal for a detailed map between wrapped D-branes in Anti-de Sitter space and baryon-like operators in the associated dual conformal field theory provided in hep-th/0202150 to the recently formulated AdS4 × CP/ABJM correspondence. In this example, the role of the dibaryon operator of the 3dimensional CFT is played by a D4-brane wrapping a CP ⊂ CP. This topologically stable D-br...
