    • A (0,2) mirror duality 

      Bertolini, Marco; Plesser, M Ronen
      We construct a class of exactly solved (0,2) heterotic compactifications, similar to the (2,2) models constructed by Gepner. We identify these as special points in moduli spaces containing geometric limits described ...

    • Coarse-graining quivers 

      Narayan, K; Plesser, M Ronen
      We describe a block-spin-like transformation on a simplified subset of the space of supersymmetric quiver gauge theories that arise on the worldvolumes of D-brane probes of orbifold geometries, by sequentially Higgsing the ...

    • Elusive Worldsheet Instantons in Heterotic String Compactifications 

      Aspinwall, Paul S; Plesser, M Ronen (STRING-MATH 2011, 2012-01-01)
      We compute the spectrum of massless gauge singlets in some heterotic string compactifications using Landau-Ginzburg, orbifold and non-linear sigma-model methods. This probes the worldsheet instanton corrections ...

    • Mirror Symmetry and Discriminants 

      Aspinwall, Paul S; Plesser, M Ronen; Wang, Kangkang
      We analyze the locus, together with multiplicities, of "bad" conformal field theories in the compactified moduli space of N=(2,2) superconformal field theories in the context of the generalization of the Batyrev ...
