Uniformly Positive Correlations in the Dimer Model and Macroscopic Interacting Self‐Avoiding Walk in ℤd, d ≥ 3
L Taggi - Communications on Pure and Applied Mathematics, 2022 - Wiley Online Library
Our first main result is that correlations between monomers in the dimer model in do not

Gaussian random permutation and the boson point process
We construct an infinite volume spatial random permutation (X, σ)(X, σ), where X ⊂ R^ d X⊂

Loop correlations in random wire models
We introduce a family of loop soup models on the hypercubic lattice. The models involve
links on the edges, and random pairings of the link endpoints on the sites. We conjecture …

Scaling limit of ballistic self-avoiding walk interacting with spatial random permutations
We consider nearest neighbour spatial random permutations on \mathbbZ^d. In this case,
the energy of the system is proportional to the sum of all cycle lengths, and the system can …
