Conformal superspace sigma-models
Vladimir Mitev, Thomas Quella, Volker Schomerus
We review recent developments in the context of two-dimensional conformally invariant sigma-models. These quantum field theories play a prominent role in the covariant superstring…

Principal Chiral Model on Superspheres
Vladimir Mitev, Thomas Quella, Volker Schomerus
We investigate the spectrum of the principal chiral model (PCM) on odd-dimensional superspheres as a function of the curvature radius R. For volume-filling branes on S^{3|2}, we co…
