The role of collective motion in examples of coarsening and self-assembly
No full textThe simplest prescription for building a patterned structure from its constituents is to add particles, one at a time, to an appropriate template. However, self-organizing molecular and colloidal systems in nature can evolve in much more hierarchical ways. Specifically, constituents (or clusters of constituents) may aggregate to form clusters (or clusters of clusters) that serve as building blocks for later stages of assembly. Here we evaluate the character and consequences of such collective motion in a set of prototypical assembly processes. We do so using computer simulations in which a system's capacity for hierarchical dynamics can be controlled systematically. By explicitly allowing or suppressing collective motion, we quantify its effects. We find that coarsening within a two dimensional attractive lattice gas (and an analogous off-lattice model in three dimensions) is naturally dominated by collective motion over a broad range of temperatures and densities. Under such circumstances, cluster mobility inhibits the development of uniform coexisting phases, especially when macroscopic segregation is strongly favored by thermodynamics. By contrast, the assembly of model viral capsids is not frustrated but is instead facilitated by collective moves, which promote the orderly binding of intermediates consisting of several monomers
Magneto-optic ellipsometry characterization of Co and SmCo thin films
No full textMagneto-optic ellipsometry in the longitudinal Kerr configuration was performed to determine the complex permittivity tensor of the Co and SmCo thin films within the spectral range from 400nm to 1000nm. The Co film was a middle layer in a Au/Co/Au trilayer structure. Magneto-optical response was analyzed in terms of Mueller matrix elements. Reduced magneto-optical response of the Co layer is explained by influence of the gold top layer of the trilayer structure. Full Text: PDF ReferencesM.

Local moment problem
No full textThe work is devoted to the local moment problem, which consists in finding of non-decreasing functions on the real axis
having given first 2n+1; n = 0,1,2,...; power moments on the whole axis and also 2m+1 first power moments on a certain finite
axis interval. Considering the local moment problem as a combination of the Hausdorff and Hamburger truncated moment
problems we obtain the conditions of its solvability and describe the class of its solutions with minimal number of growth
points if the problem is solvable.Adamyan, V.; Tkachenko Gorski, IM. (2014). Local moment problem.
