Mixing by cutting-and-shuffling a hemispherical shell

Thomas F. Lynn
Engineering Sciences and Applied Mathematics
Mixing due to cutting-and-shuffling is studied at a fundamental level using 2D mappings known as Piecewise Isometries (PWI) which can create beautiful mixing patterns. The PWI studied here splits a hemispherical shell (HS) into four curved triangular pieces that are rearranged to make a shuffled HS. Applying the PWI repeatedly... View the visualization.

Cubine, a Two-Dimensional Copper–Bismuth Nanosheet

Maximilian Amsler
Materials Science and Engineering
Using ab initio calculations, we discovered a quasi two-dimensional copper–bismuth nano sheet, which we call cubine. According to our predictions, single layers of cubine can be isolated from the recently reported high-pressure CuBi bulk material at an extremely low energetic cost, comparable to values to separate single layers of graphene...

Fractals by cutting-and-shuffling a hemispherical shell

Thomas F. Lynn
Engineering Sciences and Applied Mathematics
A fractal is created by a Piecewise Isometry (PWI) which cuts a 2D object into pieces and rearranges those pieces to recreate the original object in a scrambled form. The PWI studied here splits a hemispherical shell into four pieces along cutting lines and rearranges them into a shuffled hemisphere.... View the visualization.
