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 improvement on the bound for analyticity is by a factor $e^2$ over the classical cluster expansion approach and a factor $e$ over the known limit of cluster expansion convergence. The criterion is based on a contractive property of a recursive computation of the density of a point process. The key ingredients in our proofs… 
A Spectral Independence View on Hard Spheres via Block Dynamics
TLDR
This work proposes a Markov chain Monte Carlo algorithm for approximating the grand-canonical partition function of the hard-sphere model in d dimensions and proves rapid mixing of clique dynamics up to the tree threshold of the univariate hard-core model.
Algorithms for general hard-constraint point processes via discretization
TLDR
Key to the method is reducing the continuous model to a discrete instance of the hard-core model with size polynomial in ν (V), which generalizes existing discretization schemes for thehard-sphere model and improves the required number of vertices of the generated graph from super-exponential to quadratic inν ( V), which the authors argue to be tight.
Potential-weighted connective constants and uniqueness of Gibbs measures
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 underlying space. We
An explicit Dobrushin uniqueness region for Gibbs point processes with repulsive interactions
We present a uniqueness result for Gibbs point processes with interactions that come from a non-negative pair potential; in particular, we provide an explicit uniqueness region in terms of activity z
Correlation decay for hard spheres via Markov chains
TLDR
This work improves upon all known lower bounds on the critical fugacity and critical density of the hard sphere model in dimensions two and higher and proves an equivalence between optimal spatial and temporal mixing for hard spheres.
Five lectures on statistical mechanics methods in combinatorics
polymer models provide a way to completely abstract these two properties, and they provide a natural setting in which to apply the cluster expansion. Abstract polymer models were introduced by
Revisiting Groeneveld’s approach to the virial expansion
A generalized version of Groeneveld's convergence criterion for the virial expansion and generating functionals for weighted $2$-connected graphs is proven. The criterion works for inhomogeneous

Spatial mixing and the connective constant: Optimal bounds
TLDR
The best possible rates of decay of correlations in the natural probability distributions induced by both the hard core model and the monomer-dimer model are proved in graphs with a given bound on the connective constant.

TLDR
It is shown that on any graph of maximum degree Δ correlations decay with distance at least as fast as they do on the regular tree of the same degree, which resolves an open conjecture in statistical physics.

The Gibbs point processes (GPP) constitute a large class of point processes with interaction between the points. The interaction can be attractive, repulsive, depending on geometrical features

Abstract We find an improved estimate of the radius of analyticity of the pressure of the hard-sphere gas in d dimensions. The estimates are determined by the volume of multidimensional regions that
