A Compact Codimension Two Braneworld with Precisely One Brane
Nikolas Akerblom, Gunther Cornelissen
Building on earlier work on football shaped extra dimensions, we construct a compact codimension two braneworld with precisely one brane. The two extra dimensions topologically rep…
Nonrelativistic Chern-Simons Vortices on the Torus
Nikolas Akerblom, Gunther Cornelissen, Gerben Stavenga +1
A classification of all periodic self-dual static vortex solutions of the Jackiw-Pi model is given. Physically acceptable solutions of the Liouville equation are related to a class…
Marginal Deformations and 3-Algebra Structures
Nikolas Akerblom, Christian Saemann, Martin Wolf
We study marginal deformations of superconformal Chern-Simons matter theories that are based on 3-algebras. For this, we introduce the notion of an associated 3-product, which capt…
D-brane Instantons in 4D Supersymmetric String Vacua
Nikolas Akerblom, Ralph Blumenhagen, Dieter Lust +1
We review some aspects of D-instantons in intersecting D-brane models. In particular, we present applications of the recently proposed instanton calculus to computations of charged…
Instantons and Holomorphic Couplings in Intersecting D-brane Models
Nikolas Akerblom, Ralph Blumenhagen, Dieter Lust +1
We clarify certain aspects and discuss extensions of the recently introduced string D-instanton calculus (hep-th/0609191). The one-loop determinants are related to one-loop open st…
Thresholds for Intersecting D-branes Revisited
Nikolas Akerblom, Ralph Blumenhagen, Dieter Lust +1
Gauge threshold corrections for intersecting D6-brane string models on toroidal orbifold backgrounds are reconsidered. Both by dimensionally regularising the appearing open string…
