D-branes in group manifolds and flux stabilization
Christoph Schweigert
We consider D-branes in group manifolds, from the point of view of open strings and using the Born-Infeld action on the brane worldvolume. D-branes correspond to certain integral (…
Conformal field theory, boundary conditions and applications to string theory
C. Schweigert, J. Fuchs, J. Walcher
This is an introduction to two-dimensional conformal field theory and its applications in string theory. Modern concepts of conformal field theory are explained, and it is outlined…
Solitonic sectors, conformal boundary conditions and three-dimensional topological field theory
C. Schweigert, J. Fuchs
The correlation functions of a two-dimensional rational conformal field theory, for an arbitrary number of bulk and boundary fields and arbitrary world sheets can be expressed in t…
Boundaries, crosscaps and simple currents
J. Fuchs, L. R. Huiszoon, A. N. Schellekens +2
Universal formulas for the boundary and crosscap coefficients are presented, which are valid for all symmetric simple current modifications of the charge conjugation invariant of a…
Boundary Fixed Points, Enhanced Gauge Symmetry and Singular Bundles on K3
J. Fuchs, P. Kaste, W. Lerche +3
We investigate certain fixed points in the boundary conformal field theory representation of type IIA D-branes on Gepner points of K3. They correspond geometrically to degenerate b…
D-Branes on ALE Spaces and the ADE Classification of Conformal Field Theories
W. Lerche, A. Lutken, C. Schweigert
The spectrum of D2-branes wrapped on an ALE space of general ADE type is determined, by representing them as boundary states of N=2 superconformal minimal models. The stable quantu…
