Pattern Formations in Active Matter Physics

Physics of Granular Matter: Pattern Formation and Applications

A summary of results is presented from experiments in granular systems, which are excited by vertical and/or horizontal vibrations. The transitions between different dynamic states depend on internal properties of the granular system like the density of particles and on external parameters of the driving shakers. Characteristic for granular systems are such counterintuitive phenomena as the cry...

Mosaic Pattern Formations in Multicellular Chemical Systems

A 2-dimensional array of coupled Brusselators cells is studied numerically. A variety of stationary patterns are obtained depending on the coupling strength of an activator and an inhibitor. Mosaic patterns of different motifs, in a very complicated spatial arrangement, are discovered. The mechanism that leads to the formation of the mosaic patterns consists of the formation of rings by an osci...

Physics of Strange Matter

All known nuclei are made of the two nucleons, the proton and the neutron. Besides those two lightest baryons there exist still a couple of other stable (but weakly decaying) baryons, the hyperons. These were found for the first time in cosmic ray experiments and were entitled as ‘strange’ because of their unusual long lifetimes of about 10−10 sec. For their notation in the hadron zoo of elemen...
