A Cellular Representation of the Potts Lattice Higgs Model
Summer Eldridge, Malin P. Forsström, Benjamin Schweinhart
The -dimensional Potts lattice Higgs model is a random assignment of spins in to the -dimensional cells of a cell complex induced by a Hamiltonian with a Potts…
Phase transitions in the charged compact abelian lattice Higgs model
Malin Palö Forsström
We consider the (compact) abelian lattice Higgs model with charge \( k \geq 1 \) and show, using charged Wilson~loop observables and charged versions of the Marcu--Fredenhagen rati…
Ornstein-Zernike decay of Wilson line observables in the free phase of the \( \mathbb{Z}_2 \) lattice Higgs model
Malin Palö Forsström
In the physics literature, the Wilson line observable is believed to have a phase transition between a region with pure exponential decay and a region with Ornstein-Zernike type co…
Current expansion and couplings for Ising lattice gauge theory
Malin P. Forsström, Fredrik Viklund
In this note, we discuss a random current expansion and a switching lemma for Ising lattice gauge theory at all choices of inverse temperature , leading to summation over surfac…
Mixing for Poisson representable processes and consequences for the Ising model and the contact process
Stein Andreas Bethuelsen, Malin Palö Forsström
Forsström et al. [8] recently introduced a large class of -valued processes that they named Poisson representable. In addition to deriving several interesting properties f…
Poisson representations for tree-indexed Markov chains
Malin Palö Forsström
In~\cite{fgs}, the class of Poisson representable processes was introduced. Several well-known processes were shown not to belong to this class, with examples including both the Cu…
The phase transition of the Marcu-Fredenhagen ratio in the abelian lattice Higgs model
Malin P. Forsström
The Marcu-Fredenhagen ratio is a quantity used in the physics literature to differentiate between phases in lattice Higgs models. It is defined as the limit of a ratio of expectati…
Free energy and quark potential in Ising lattice gauge theory via cluster expansion
Malin Palö Forsström, Fredrik Viklund
We revisit the cluster expansion for Ising lattice gauge theory on with Wilson action, at a fixed inverse temperature \( β\) in the low-temperature regi…
Decay of correlations in finite Abelian lattice gauge theories
Malin Palö Forsström
In this paper, we study lattice gauge theory on \( \mathbb{Z}^4 \) with finite Abelian structure group. When the inverse coupling strength is sufficiently large, we give an upper b…
When are sequences of Boolean functions tame?
Malin Palö Forsström
In \cite{js2006}, Jonasson and Steif conjectured that no non-degenerate sequence of transitive Boolean functions with cou…
A tame sequence of transitive Boolean functions
Malin Palö Forsström
Given a sequence of Boolean functions , , and a sequence of continuous time -biased random wa…
A Few Surprising Integrals
Malin Palö Forsström, Jeffrey E. Steif
Using formulas for certain quantities involving stable vectors, due to I. Molchanov, and in some cases utilizing the so-called divide and color model, we prove that certain familie…
Divide and color representations for threshold Gaussian and stable vectors
Malin Palö Forsström, Jeffrey E. Steif
We study the question of when a (\{0,1\})-valued threshold process associated to a mean zero Gaussian or a symmetric stable vector corresponds to a {\it divide and color (DC) proce…
Denseness of volatile and nonvolatile sequences of functions
Malin Palö Forsström
In a recent paper by Jonasson and Steif, definitions to describe the volatility of sequences of Boolean functions, \( f_n \colon \{ -1,1 \}^n \to \{ -1,1 \} \) were introduced. We…
Exact Hausdorff measures of Cantor sets
Malin Palö Forsström
Cantor sets in \(\mathbb{R}\) are common examples of sets for which Hausdorff measures can be positive and finite. However, there exist Cantor sets for which no Hausdorff measure i…
Noise Sensitivity and Noise Stability for Markov Chains: Existence Results
Malin Palö Forsström
During the past 15 years, several extensions of the concepts noise sensitivity and noise stability, first coined in~\cite{schramm2000}, has been studied. The purpose in this paper…
A Noise Sensitivity Theorem for Schreier Graphs
Malin Palö Forsström
During the past 15 years, several extensions of the concept of noise sensitivity first coined in~\cite{schramm2000}, has been studied. One such extension was studied in ??, where t…
