Journal ArticleDOI
Defect conformal field theory and locally localized gravity
TL;DR: In this paper, the authors examined the defect conformal field theory from the point of view of the holographic dual model and showed that a very light localized graviton exists when a mode arising from the reduction of the ambient stress-energy tensor to the defect has conformal dimension? ~ d?1.
Journal ArticleDOI
Branes and six dimensional fixed points
Ilka Brunner,Andreas Karch +1 more
TL;DR: In this paper, the authors analyze brane configurations corresponding to non-trivial six-dimensional fixed points and derive several results previously obtained from a pure field theoretical analysis in the brane language.
Journal ArticleDOI
Equivalence of geometric engineering and Hanany-Witten via fractional branes
TL;DR: In this paper, the authors present an explicit relation between the Hanany-Witten and Geometric Engineering approaches of realizing gauge theories in string theory. And the last piece in the puzzle is a T -duality relating arbitrary HananyWitten setups and fractional branes.
Journal ArticleDOI
Mirror symmetries for brane configurations and branes at singularities
TL;DR: In this paper, the authors study local mirror symmetry on non-compact Calabi-Yau manifolds in the presence of D3 brane probes and show that using an intermediate brane setup of NS 5-branes 'probed' by D-brane probes can explicitly T-dualize three isometry directions to relate a noncompact CYau manifold to its local mirror.
Journal ArticleDOI
Revisiting non-relativistic limits
Kristan Jensen,Andreas Karch +1 more
TL;DR: In this paper, it was shown that the full spurionic symmetry of Galilean invariant field theories can be deduced when those theories are the limits of relativistic parents, and that the non-relativistic daughter couples to Newton-Cartan geometry together with all of the symmetries advocated in previous work.
