Shannon Horrigan

Research:

I am currently a final year PhD student as part of the University of Warwick's MASDOC Doctoral Training Programme. My research is in the area of Statistical Mechanics. I am currently working with Dr. Stefan Adams on a class of continuum models in two dimensions known as Delaunay Potts models. We are investigating whether such models exhibit a phase transition.

Publications and Preprints:

[1] S. Adams and S. Horrigan, "Phase transition for Gibbs Delaunay Tessellations with geometric hardcore conditions", preprint, arXiv:2104.05108.

[2] S. Horrigan, "Continuum Random Cluster and Potts models with Delaunay interactions," PhD Thesis. (Here is the current draft, minor revisions are still to be made)
