Closed string tachyons in a smooth curved background
Pedro Bordalo
Closed string tachyon condensation has been studied in orbifolds C^2/Z_{N,p} of flat space, using the chiral ring of the underlying N=2 conformal field theory. Here we show that si…
Towards Quantum Dielectric Branes: Curvature Corrections in Abelian Beta Function and Nonabelian Born-Infeld Action
Pedro Bordalo, Lorenzo Cornalba, Ricardo Schiappa
We initiate a programme to compute curvature corrections to the nonabelian BI action. This is based on the calculation of derivative corrections to the abelian BI action, describin…
Discrete Torsion and WZW Orbifolds
Pedro Bordalo
We propose a geometrical interpretation for the discrete torsion appearing in the algebraic formulation of quotients of WZW models by discrete abelian subgroups. Part of the discre…
D-branes in lens spaces
P. Bordalo, A. Wurtz
We realize the CFT with target a lens space SU(2)/Z_l as a simple current construction. This allows us to compute the boundary states and the annuli coefficients, and in particular…
Flux stabilization in compact groups
Pedro Bordalo, Sylvain Ribault, Christoph Schweigert
We consider the Born-Infeld action for symmetry-preserving, orientable D-branes in compact group manifolds. We find classical solutions that obey the flux quantization condition. T…
