  • Beyond the standard gauging: gauge symmetries of Dirac sigma models 
    Chatzistavrakidis, Athanasios; Deser, Andreas; Jonke, Larisa; Strobl, Thomas (Heidelberg : Springer Verlag, 2016)
    In this paper we study the general conditions that have to be met for a gauged extension of a two-dimensional bosonic σ-model to exist. In an inversion of the usual approach of identifying a global symmetry and then promoting ...
  • Sigma-model limit of Yang–Mills instantons in higher dimensions 
    Deser, Andreas; Lechtenfeld, Olaf; Popov, Alexander D. (Amsterdam : Elsevier Science BV, 2015)
    We consider the Hermitian Yang–Mills (instanton) equations for connections on vector bundles over a 2n-dimensional Kähler manifold Xwhich is a product Y×Zof p-and q-dimensional Riemannian manifold Yand Zwith p+q=2n. We ...
  • T-duality without isometry via extended gauge symmetries of 2D sigma models 
    Chatzistavrakidis, Athanasios; Deser, Andreas; Jonke, Larisa (New York : Springer, 2016)
    Target space duality is one of the most profound properties of string theory. However it customarily requires that the background fields satisfy certain invariance conditions in order to perform it consistently; for instance ...
