Ising models on locally tree-like graphs
Ising model random sparse graphs cavity method Bethe measures belief propagation local weak convergence
2015/8/21
We consider Ising models on graphs that converge locally to trees. Examples include random regular graphs with bounded degree and uniformly random graphs with bounded average degree. We prove that the...
The weak limit of Ising models on locally tree-like graphs
Ising model the temperature the last beta sequence
2015/8/20
We consider the Ising model with inverse temperature β and without external field on sequences of graphs Gn which converge locally to the k-regular tree. We show that for such graphs the Ising m...
Sparse Ising Models with Covariates
Graphical model Lasso Ising model Binary Markov network covariates
2012/11/23
There has been a lot of work fitting Ising models to multivariate binary data in order to understand the conditional dependency relationships between the variables. However, additional covariates are ...
Self-similar transformations of lattice-Ising models at critical temperatures
Self-similar transformations lattice-Ising models critical temperatures General Physics
2012/5/29
We classify geometric blocks that serve as spin carriers into simple blocks and compound blocks by their topologic connectivity, define their fractal dimensions and describe the relevant transformatio...
Fat-tailed and compact random-field Ising models on cubic lattices
Random-Field Ising Model Fat tails Compact distributions
2010/11/23
Using a single functional form which is able to represent several different classes of
statistical distributions, we introduce a preliminary study of the ferromagnetic Ising model
on the cubic latti...
Gibbs-non-Gibbs properties for evolving Ising models on trees
non-Gibbsianness Ising models tree graphs Glauber dynamics
2010/12/7
In this paper we study homogeneous Gibbs measures on a Cayley tree,subjected to an in nite-temperature Glauber evolution, and consider their (non-)Gibbsian properties. We show that the intermediate Gi...
Exact results for the criticality of quench dynamics in quantum Ising models
Exact results criticality of quench dynamics quantum Ising models
2010/4/12
Based on the obtained exact results we systematically study the quench dynamics of a one-dimensional spin-1/2 transverse field Ising model with zero- and finite-temperature initial states. We focus on...
