Disorder is an unavoidable ingredient of real systems. Spatial disorder generates Griffiths phases (GPs) which, in analogy to critical points, are characterized by a slow relaxation of the order parameter and divergences of quantities such as the susceptibility. However, these singularities appear in an extended region of the parameter space and not just at a (critical) point, i.e., there is ge...

Transient phase dynamics, synchronization, and desynchronization which are stimulus-locked (i.e., tightly time-locked to a repetitively administered stimulus) are studied in two coupled phase oscillators in the presence of noise. The presented method makes it possible to detect such processes in numerical and experimental signals. The time resolution is enormous, since it is only restricted by ...

Various engineered domain configurations were induced into barium titanate (BaTiO3) single crystals, and their piezoelectric properties were investigated as a function of (1) the crystal structure, (2) the crystallographic orientation and (3) the domain size. As a result, the orthorhombic mm2 BaTiO3 crystals showed the highest piezoelectric properties among three kinds of BaTiO3 crystals such a...

Analysis and design algorithms for residual generators for non minimum phase systems are given. It is shown that Rm optimization of residual generators applied directly to systems including non m i n i u m phase zeros can be very conservative. To remove this conservatism in the H, optimization of the residual generators, a factorization of the non minimum phase system into a minimum phase part ...

In the present study we demonstrate that a bulk inverse micellar cubic phase of Fd3m structure can be obtained by adding a hydrophobic component, such as the food-grade limonene, to the binary system monolinolein/water in a well-defined composition. The Fd3m structure studied in this work had a very slow kinetics of formation, as a consequence of partitioning of water into two types of micelle ...

On the basis of the principle that topological quantum phases arise from the scattering around space-time defects in higher dimensional uniication, a geometric model is presented that associates with each quantum phase an element of a transformation group.

We study classical and quantum phases in the adiabatic BornOppenheimer context. These include a classical astronomical case, the general dual description of the phases, a new “Paradox” connected to scattering Berry phase and its resolution and various elaboration of topological/geometrical/non-abelian phases.
