Hard-disk pressure computations—a historic perspective

B Li, Y Nishikawa, P Höllmer, L Carillo… - The Journal of …, 2022 - pubs.aip.org
We discuss pressure computations for the hard-disk model performed since 1953 and
compare them to the results that we obtain with a powerful event-chain Monte Carlo and a …

A spectral independence view on hard spheres via block dynamics

T Friedrich, A Göbel, MS Krejca, M Pappik - SIAM Journal on Discrete …, 2022 - SIAM
The hard-sphere model is one of the most extensively studied models in statistical physics. It
describes the continuous distribution of spherical particles, governed by hard-core …

Perfect sampling for hard spheres from strong spatial mixing

K Anand, A Göbel, M Pappik, W Perkins - arxiv preprint arxiv:2305.02450, 2023 - arxiv.org
We provide a perfect sampling algorithm for the hard-sphere model on subsets of $\mathbb
{R}^ d $ with expected running time linear in the volume under the assumption of strong …

Analyticity for classical gasses via recursion

M Michelen, W Perkins - Communications in Mathematical Physics, 2023 - Springer
We give a new criterion for a classical gas with a repulsive pair potential to exhibit
uniqueness of the infinite volume Gibbs measure and analyticity of the pressure. Our …

Large-scale dynamics of event-chain Monte Carlo

AC Maggs, W Krauth - Physical Review E, 2022 - APS
Event-chain Monte Carlo (ECMC) accelerates the sampling of hard-sphere systems, and
has been generalized to the potentials used in classical molecular simulations. Rather than …

Potential-weighted connective constants and uniqueness of Gibbs measures

M Michelen, W Perkins - arxiv preprint arxiv:2109.01094, 2021 - arxiv.org
We define a potential-weighted connective constant that measures the effective strength of a
repulsive pair potential of a Gibbs point process modulated by the geometry of the …

Strong spatial mixing for repulsive point processes

M Michelen, W Perkins - Journal of Statistical Physics, 2022 - Springer
We prove that a Gibbs point process interacting via a finite-range, repulsive potential ϕ
exhibits a strong spatial mixing property for activities λ< e/Δ ϕ, where Δ ϕ is the potential …

Sampling repulsive Gibbs point processes using random graphs

T Friedrich, A Göbel, M Katzmann… - Combinatorics …, 2025 - cambridge.org
We study computational aspects of repulsive Gibbs point processes, which are probabilistic
models of interacting particles in a finite-volume region of space. We introduce an approach …

Damage spreading and coupling in spin glasses and hard spheres

K Hukushima, W Krauth - arxiv preprint arxiv:2410.05544, 2024 - arxiv.org
We study the connection between damage spreading, a phenomenon long discussed in the
physics literature, and the coupling of Markov chains, a technique used to bound the mixing …

[HTML][HTML] Revisiting Groeneveld's approach to the virial expansion

S Jansen - Journal of Mathematical Physics, 2021 - pubs.aip.org
A generalized version of Groeneveld's convergence criterion for the virial expansion and
generating functionals for weighted two-connected graphs is proven. This criterion works for …
