This paper studies the tendency of two dimensional topological defects of large defect strength to break up into elementary units. The authors study the process and the resulting structures theoretically for different ways of enforcing the defects, and test some of their predictions experimentally in nematic liquid crystals.

This paper studies transport in a quantum spin chain driven by particular boundary terms, and identifies a family of stationary solutions. The solutions are current-carrying nonequilibrium states that correspond to ballistic transport, and whose properties depend on the details of the boundary terms.

This paper proposes an explanation for the relatively uniform size of conifer needles, as compared with the leaves of broad-leaved plants. The explanation lies in the particular dynamics of sugar transport, as larger needlelike leaves would create regions of stagnant fluid that cannot be overcome by the vascular osmotic pressure.

This paper aims to extend the first-passage problem to quantum walks. Starting from the Schrödinger equation and applying projective measurements at fixed time intervals, the authors construct the statistics of first detection times for open and closed systems. The results are quite different from those for classical random walks, although some similarities remain.
