Phason elasticity and atomic dynamics of quasicrystals
As the order of a quasicrystal is quasiperiodic, it can be described as an irrational cut through a periodic structure in a higher-dimensional space. This mathematical trick has important consequences for the low energy excitations that can occur. Translating the cut space to a different position is a symmetry operation, which changes the quasicrystal structure, but not its energy. A small brea...
متن کاملNeural statics and dynamics
A formal theory of systems was proposed previously as providing a quantitative basis for neural computation. This theory dictated the architectural aspects of a pyramidal-neuron system model including its operation, adaptation, and most importantly, its computational objective. The principal result was a perceptron architecture that, through adaptation, learns to ask a specific space–time quest...
متن کاملChemical Statics and Dynamics
This is one of the text-books of Physical Chemistry edited by Sir Willam Ramsay. It views chemistry from the standpoint of the explanation of its phenomena by the physical laws which govern appreciable weights of substances, and it is shown that they operate equally in the changes which take place between individual mollecules during chemical reaction. It is pleasant to find that sharp distinct...
متن کاملPhason dynamics in nonlinear photonic quasicrystals.
We study the dynamics of phasons in a nonlinear photonic quasicrystal. The photonic quasicrystal is formed by optical induction, and its dynamics is initiated by allowing the light waves inducing the quasicrystal to nonlinearly interact with one another. We show quantitatively that, when phason strain is introduced in a controlled manner, it relaxes through the nonlinear interactions within the...
متن کاملComplex networks: Statics and Dynamics
We present some of the results obtained during the last 8 years about complex networks. Starting with the collection of data in the form of networks or graphs, we proceed on the characterization at different scales: microscopic, macroscopic, and mesoscopic. We introduce also the basic models incorporating complexity in the pattern of connectivities. Finally we review some results on dynamical f...
