5. Upper bounds for the connective constant of weighted self-avoiding walks. 2025. [arXiv | GitHub]
Building on an earlier work by Alm, I develop a computational method for deriving upper bounds on the connective constant of weighted self-avoiding walks. A Python implementation of the method is publicly available.
4. Analyticity for locally stable hard-core gases via recursion. Journal of Statistical Physics, 2025. [arXiv | journal]
Extending the recursion method developed by Michelen–Perkins, I expand the known range of activities for which a continuum system of hard spheres with an additional attractive pair interaction is in the gas phase. In the high-temperature regime, the improvement surpasses the classical Penrose-Ruelle bound by at least a factor of e^2.
3. High-fugacity expansion and crystallization in non-sliding hard-core lattice particle systems without a tiling constraint; with Ian Jauslin. Journal of Statistical Physics, 2024. [arXiv | journal]
We prove that a large class of hard-core lattice particle models crystallize at high densities, using a novel characterization of local order based on discrete Voronoi diagrams.
