A gluing operator for the ambitwistor string
We present a new operator in the ambitwistor string which glues together correlators with fewer points or of lower genus. It underpins the recursive construction of tree-level CHY scattering amplitudes by Dolan & Goddard, ...

BPS Approaches to Anyons, Quantum Hall States and Quantum Gravity
(University of CambridgeDAMTP (Mathematics)Trinity College, 2017-10-03)We study three types of theories, using supersymmetry and ideas from string theory as tools to gain understanding of systems of more general interest. Firstly, we introduce non-relativistic Chern-Simons-matter field ...
