Lattice random-field Widom--Rowlinson models
Benedikt Jahnel, Daniel Kamecke, Christof Külske
We consider the Widom--Rowlinson model on subject to a symmetric i.i.d.\ random field. We prove that for dimensions any non-trivial random field leads to an…
-dimensional spherical ferromagnets in random fields: Metastates, continuous symmetry breaking, and spin-glass features
Kalle Koskinen, Christof Külske
We study the large-volume behavior of the spherical model for -dimensional local spins, in the presence of -dimensional random fields, for . We compare two models, o…
Locality properties for discrete and continuum Widom--Rowlinson models in random environments
Benedikt Jahnel, Christof Külske, Alexander Zass
We consider the Widom--Rowlinson model in which hard balls of two possible colors are constrained to a hard-core repulsion between particles of different colors, in quenched random…
Gibbs Properties of the Bernoulli field on inhomogeneous trees under the removal of isolated sites
Florian Henning, Christof Külske, Niklas Schubert
We consider the i.i.d. Bernoulli field with occupation density on a possibly non-regular countably infinite tree with bounded degrees. For large , we show th…
Extremal decomposition for random Gibbs measures: From general metastates to metastates on extremal random Gibbs measures
Codina Cotar, Benedikt Jahnel, Christof Külske
The concept of metastate measures on the states of a random spin system was introduced to be able to treat the large-volume asymptotics for complex quenched random systems, like sp…
Nonexistence of random gradient Gibbs measures in continuous interface models in
Aernout C. D. van Enter, Christof Külske
We consider statistical mechanics models of continuous spins in a disordered environment. These models have a natural interpretation as effective interface models. It is well known…
