I'm excited to share that my new website, Scift (www.scift.app), is now live!
Scift is a simple way to explore scientific preprints from across all areas of science — no ratings, no comments, just the papers to read and consider on your own terms.

I'm pleased that our paper on a graph-theoretic framework for free-parafermion solvability has been published in RSPA. We prove that if the frustration graph of a spin system is an oriented indifference graph, then it has an exact free-parafermion solution. royalsocietypublishing.org/doi/10.1098/...

New paper with Samuel Elman, David Wood, and Adrian Chapman! We provide a graph-theoretic characterisation of when a quantum spin system can be solved via a mapping to free parafermions.
