Curvature-amplified angular localization of radially localized states
Hiroyuki Shima
We study a continuum Schrödinger particle on a surface of constant curvature subject to a radial random potential and a weaker angle-dependent perturbation. Exact angular-momentum…
Geometric Renormalization and a Chirality Threshold in Recursively Coiled Filaments
Hiroyuki Shima
Repeated coiling creates a filament hierarchy. We formulate helicalization as an iterated map acting on an arbitrary rod compliance, rather than homogenizing one prescribed constru…
Empirical rule of fruit rind fragmentation in muskmelon netting
Yuri Akiba, Akari Ishibashi, Motohiro Sato +1
The suberized netting tissue on the surface of muskmelons is a remnant of the rind fragmentation caused by the mechanical imbalance between the expanding flesh meat and the solidif…
Universal fluctuation of polygonal crack geometry in solidified lava
Yuri Akiba, Aika Takashima, Hiroyuki Shima
Outcrops of columnar joints made of solidified lava flows are often covered by semi-ordered polygonal cracks. The polygon diameters are fairly uniform at each outcrop, but their sh…
Simple approximate formulas for postbuckling deflection of heavy elastic columns
Hiroyuki Shima
Columnar buckling is a ubiquitous phenomenon that occurs in both living things and man-made objects, regardless of the length scale ranging from macroscopic to nanometric structure…
Scaling law for the onset of the surface wrinkling of multilayer tubes
Motohiro Sato, Kazusa Ishigami, Hiroyuki Kato +2
Surface wrinkling is an instability mode that is often observed in a wide variety of multilayer tubes under bending deformation. When the degree of applied bending exceeds a critic…
