    • Finite deformations from a heterotic superpotential: holomorphic Chern-Simons and an L∞ algebra 

      Ashmore, Anthony; de la Ossa, Xenia; Minasian, Ruben; Strickland-Constable, Charles; Svanes, Eirik Eik (2018-10-29)
      We consider finite deformations of the Hull-Strominger system. Starting from the heterotic superpotential, we identify complex coordinates on the off-shell parameter space. Expanding the superpotential around a supersymmetric ...
    • Topological G 2 and Spin(7) strings at 1-loop from double complexes 

      Ashmore, Anthony; Coimbra, André; Strickland-Constable, Charles; Svanes, Eirik Eik; Tennyson, David (2022-02-11)
      We study the topological G2 and Spin(7) strings at 1-loop. We define new double complexes for supersymmetric NSNS backgrounds of string theory using generalised geometry. The 1-loop partition function then has a target-space ...
