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…
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 surfa…
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…
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…
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…
