Survival of short-range order in the Ising model on negatively curved surfaces
Yasunori Sakaniwa, Hiroyuki Shima
We examine the ordering behavior of the ferromagnetic Ising lattice model defined on a surface with a constant negative curvature. Small-sized ferromagnetic domains are observed to…

Phase transition of -state clock models on heptagonal lattices
Seung Ki Baek, Petter Minnhagen, Hiroyuki Shima +1
We study the -state clock models on heptagonal lattices assigned on a negatively curved surface. We show that the system exhibits three classes of equilibrium phases; in between…
