Laplacian networks: growth, local symmetry and shape optimization
O. Devauchelle, P. Szymczak, M. Pecelerowicz +3
Inspired by river networks and other structures formed by Laplacian growth, we use the Loewner equation to investigate the growth of a network of thin fingers in a diffusion field.…
Long-time evolution of sequestered CO in porous media
Yossi Cohen, Daniel H. Rothman
CO sequestration in subsurface reservoirs is important for limiting atmospheric CO concentrations. However, a complete physical picture able to predict the structure develo…
Where do rivers grow? Path selection and growth in a harmonic field
Yossi Cohen, Olivier Devauchelle, Hansjorg F. Seybold +3
River networks exhibit a complex ramified structure that has inspired decades of studies. Yet, an understanding of the propagation of a single stream remains elusive. Here we invok…
Elastic Moduli in Nano-Size Samples of Amorphous Solids: System Size Dependence
Yossi Cohen, Itamar Procaccia
This Letter is motivated by some recent experiments on pan-cake shaped nano-samples of metallic glass that indicate a decline in the measured shear modulus upon decreasing the samp…
The nature of the β-peak in the loss modulus of amorphous solids
Yossi Cohen, Smarajit Karmakar, Itamar Procaccia +1
Glass formers exhibit, upon an oscillatory excitation, a response function whose imaginary and real parts are known as the loss and storage moduli respectively. The loss modulus ty…
Stress Intensity Factor of Mode III Cracks in Thin Sheets
Yossi Cohen, Itamar Procaccia
The stress field at the tip of a crack of a thin plate of elastic material that is broken due to a mode III shear tearing has a universal form with a non-universal amplitude, known…
