Convex order and faster transmission in first contact percolation

Benedikt Jahnel, Jonas Köppl, Lukas Lüchtrath +1

Inspired by strict-monotonicity criteria for the time constant in first passage percolation, we investigate convex ordering of point processes in relation to the time constant in f…

Restriction and mixing properties of interacting particle systems with unbounded range

Benedikt Jahnel, Jonas Köppl

We consider interacting particle systems with unbounded interaction range on general countably infinite graphs and prove explicit non-asymptotic error bounds for approximations…

Local criteria for global connectivity comparisons: beyond stochastic domination

Johannes Bäumler, Benedikt Jahnel, Jonas Köppl +3

We introduce a site-wise domination criterion for local percolation models, which enables the comparison of one-arm probabilities even in the absence of stochastic domination. The…

Reversible birth-and-death dynamics in continuum: a de Bruijn-type identity for free-energy dissipation

Benedikt Jahnel, Jonas Köppl, Yannic Steenbeck +1

We investigate free-energy dissipation in a continuous-time birth-and-death dynamics in . For these Markov processes, the class of reversible measures coincides with…

The variational principle for a marked Gibbs point process with infinite-range multibody interactions

Benedikt Jahnel, Jonas Köppl, Yannic Steenbeck +1

We prove the Gibbs variational principle for the Asakura--Oosawa model in which particles of random size obey a hardcore constraint of non-overlap and are additionally subject to a…

Dynamical Gibbs Variational Principles for Irreversible Interacting Particle Systems with Applications to Attractor Properties

Benedikt Jahnel, Jonas Köppl

We consider irreversible translation-invariant interacting particle systems on the -dimensional cubic lattice with finite local state space, which admit at least one Gibbs measu…
