Aspects of Topological String Theory [PDF]
, 2008 Two aspects of the topological string and its applications are considered in this thesis. Firstly, non-perturbative contributions to the OSV conjecture relating four-dimensional extremal black holes and the closed topological string partition function ...

Holographic RG flows in $$N=4$$ N=4 SCFTs from half-maximal gauged supergravity
European Physical Journal C: Particles and Fields, 2018 We study four-dimensional $$N=4$$ N=4 gauged supergravity coupled to six vector multiplets with semisimple gauge groups $$SO(4)\times SO(4)$$ SO(4)×SO(4) , $$SO(3,1)\times SO(3,1)$$ SO(3,1)×SO(3,1) and $$SO(4)\times SO(3,1)$$ SO(4)×SO(3,1) . All of these

Double field theory and geometric quantisation
Journal of High Energy Physics, 2021 We examine various properties of double field theory and the doubled string sigma model in the context of geometric quantisation. In particular we look at T-duality as the symplectic transformation related to an alternative choice of polarisation in the ...

Supersymmetrical string theories
Physics Letters B, 1982 A supersymmetrical light-cone-gauge string action is presented. It provides a basis for understanding the previously-studied supersymmetrical dual string theory as well as two new closed-string theories that have extended supersymmetry in ten dimensions, corresponding to N = 8 supersymmetry in four dimensions.

Two-dimensional SCFTs from matter-coupled $$7D~N=2$$ 7DN=2 gauged supergravity
European Physical Journal C: Particles and Fields, 2019 We study supersymmetric $$AdS_3\times M^4$$ AdS3×M4 solutions of $$N=2$$ N=2 gauged supergravity in seven dimensions coupled to three vector multiplets with $$SO(4)\sim SO(3)\times SO(3)$$ SO(4)∼SO(3)×SO(3) gauge group and $$M^4$$ M4 being a four ...

Lepton and Photon Interactions at High Energies, 2006 This talk begins with some history and basic facts about string theory and its connections with strong interactions. Comparisons of stacks of Dirichlet branes with curved backgrounds produced by them are used to motivate the AdS/CFT correspondence between superconformal gauge theory and string theory on a product of Anti-de Sitter space and a compact ...

Sequestering in string theory [PDF]
Journal of High Energy Physics, 2007 We study sequestering, a prerequisite for flavor-blind supersymmetry breaking in several high-scale mediation mechanisms, in compactifications of type IIB string theory. We find that although sequestering is typically absent in unwarped backgrounds, strongly warped compactifications do readily sequester.

SCIENTIFIC REALISM IN THE AGE OF STRING THEORY [PDF]
, 2007 String theory currently is the only viable candidate for a unified description of all known natural forces. This article tries to demonstrate that the fundamental structural and methodological differences that set string theory apart from other physical ...

Quarter-BPS states, multi-symmetric functions and set partitions
Journal of High Energy Physics, 2021 We give a construction of general holomorphic quarter BPS operators in N $$ \mathcal{N} $$ = 4 SYM at weak coupling with U(N) gauge group at finite N. The construction employs the Möbius inversion formula for set partitions, applied to multi-symmetric ...
