31 Dec 2013: New preprint! Theory of cylindrical dense packings of disks



We have previously explored cylindrical packings of disks and their relation to sphere packings. Here we extend the analytical treatment of disk packings, analysing the rules for phyllotactic indices of related structures and the variation of the density for line-slip structures, close to the symmetric ones. We show that rhombic structures, which are of a lower density, are always unstable i.e. can be increased in density by small perturbations.

13 Dec 2013: Visit by Prof. D. Weaire

Prof. D. Wearie visited us in Erlangen and gave two talks. He presented a colloquim on the structure in foams and also gave a seminar on drainage. The visit also gave us a chance to finish some work.
