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…
Growth of aqueous foam on flexible membranes
Hiroyuki Shima
In this paper, I study the coarsening dynamics of two-dimensional dry foam sandwiched by deformable membranes. The time-varying deformation of the confining membranes gives rise 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…
Multiple radial corrugations in multiwalled carbon nanotubes under pressure
Hiroyuki Shima, Motohiro Sato
Radial elastic corrugation of multiwalled carbon nanotubes under hydrostatic pressure is demonstrated by using the continuum elastic theory. Various corrugation patterns are observ…
Geometry-Driven Shift in the Tomonaga-Luttinger Exponent of Deformed Cylinders
Hiroyuki Shima, Hideo Yoshioka, Jun Onoe
We demonstrate the effects of geometric perturbation on the Tomonaga-Luttinger liquid (TLL) states in a long, thin, hollow cylinder whose radius varies periodically. The variation…
Curvature-induced frustration in the model on hyperbolic surfaces
Seung Ki Baek, Hiroyuki Shima, Beom Jun Kim
We study low-temperature properties of the spin model on a negatively curved surface. Geometric curvature of the surface gives rise to frustration in local spin configuration,…
