Continuous Transition of Defect Configuration in a Deformed Liquid Crystal Film
Isaku Hasegawa, Hiroyuki Shima
We investigate energetically favorable configurations of point disclinations in nematic films having a bump geometry. Gradual expansion in the bump width Δ gives rise to a sudden s…

Point-defect haloing in curved nematic films
Isaku Hasegawa, Hiroyuki Shima
We investigate the correlation between the point disclination energies and the surface curvature modulation of nematic liquid crystal membranes with a Gaussian bump geometry. Due t…

Novel scaling behavior of the Ising model on curved surfaces
Isaku Hasegawa, Yasunori Sakaniwa, Hiroyuki Shima
We demonstrate the nontrivial scaling behavior of Ising models defined on (i) a donut-shaped surface and (ii) a curved surface with a constant negative curvature. By performing Mon…
