Tropical symmetries of cluster algebras
James Drummond, Ãmer GürdoÄan, Jian-Rong Li
We study tropicalisations of quasi-automorphisms of cluster algebras and show that their induced action on the g-vectors can be realized by tropicalising their action on the homoge…

Light-like Wilson loop correlators
James Drummond, Ãmer GürdoÄan, Matthew Rochford +1
It is well-known that the expectation values of null polygonal Wilson loops computed in planar \(\mathcal{N}=4\) super Yang-Mills theory are dual to MHV amplitudes in that theory,…

Singularities of massless scattering and cluster algebras
Lara Bossinger, James Drummond, Ross Glew +2
Partial flag varieties arise in the context of massless scattering kinematics. They can be associated to both spinor-helicity variables and momentum twistor variables in two separa…
