Structure constants of the OSP(1|2) WZNW model
Yasuaki Hikida, Volker Schomerus
We propose exact formulas for the 2- and 3-point functions of the WZNW model on the non-compact supergroup OSP(1|2). Using the path integral approach that was recently developed in…
Branes in the GL(1|1) WZNW-Model
Thomas Creutzig, Thomas Quella, Volker Schomerus
We initiate a systematic study of boundary conditions in conformal field theories with target space supersymmetry. The WZNW model on GL(1|1) is used as a prototypical example for w…
New boundary conditions for the c=-2 ghost system
Thomas Creutzig, Thomas Quella, Volker Schomerus
We investigate a novel boundary condition for the bc system with central charge c=-2. Its boundary state is constructed and tested in detail. It appears to give rise to the first e…
Tensor products of psl(2|2) representations
Gerhard Gotz, Thomas Quella, Volker Schomerus
The aim of this work is to study finite dimensional representations of the Lie superalgebra psl(2|2) and their tensor products. In particular, we shall decompose all tensor product…
Strings through the Microscope
Volker Schomerus
Over the last few years, string theory has changed profoundly. Most importantly, novel duality relations have emerged which involve gauge theories of brane excitations on one side…
Brane Dynamics in CFT Backgrounds
Stefan Fredenhagen, Volker Schomerus
In this note we discuss bound states of un- or meta-stable brane configurations in various non-trivial (curved) backgrounds. We begin by reviewing some known results concerning bra…
