    • 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 ...

    • A heterotic Kodaira-Spencer theory at one-loop 

      Ashmore, Anthony; Ibarra, Javier José Murgas; McNutt, David Duncan; Strickland-Constable, Charles; Svanes, Eirik Eik; Tennyson, David; Winje, Sander (2023-10-23)
      We consider a heterotic version of six-dimensional Kodaira-Spencer gravityderived from the heterotic superpotential. We compute the one-loop partition function andfnd it can be expressed as a product of holomorphic Ray-Singer ...

    • 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 ...
