Heterotic backgrounds via generalised geometry: moment maps and moduli
Anthony Ashmore, Charles Strickland-Constable, David Tennyson +1
We describe the geometry of generic heterotic backgrounds preserving minimal supersymmetry in four dimensions using the language of generalised geometry. They are characterised by…

Machine learning Calabi-Yau metrics
Anthony Ashmore, Yang-Hui He, Burt Ovrut
We apply machine learning to the problem of finding numerical Calabi-Yau metrics. Building on Donaldson's algorithm for calculating balanced metrics on Kähler manifolds, we combine…

Marginal deformations of 3d CFTs from AdS backgrounds in generalised geometry
Anthony Ashmore
We study exactly marginal deformations of 3d CFTs dual to AdS solutions in eleven-dimensional supergravity using generalised geometry. Focussing on Sasaki-Einst…
