Self-assembled vortex crystals induced by inhomogeneous magnetic textures
(2019-01-01)
We investigate the self-assembly of vortices in a type-II superconducting disk subjected to highly nonuniform confining potentials produced by inhomogeneous magnetic textures. Using a series of numerical experiments performed ...
Nonlinear dynamics of short traveling capillary-gravity waves
(2005-02-01)
We establish a Green-Nagdhi model equation for capillary-gravity waves in (2+1) dimensions. Through the derivation of an asymptotic equation governing short-wave dynamics, we show that this system possesses (1 + 1) ...
Extended states in disordered doped polyacetylene chains
(1992-09-01)
In this work we study the electronic structure of ordered and disordered distributions of soliton-type defects along large, finite chains of trans-polyacetylene (trans-PA), as a function of the concentration of defects. ...
The Topology Of Dislocations In Smectic Liquid Crystals
(IOP Publishing LtdBristol, 2016)
An instrument for combining x-ray multiple diffraction and x-ray topographic imaging for examining crystal microcrystallography and perfection

Light localization in one-dimensional photonic crystal heterostructures
(2021-12-01)
Effects of both metamaterial inclusion and lack of inversion symmetry on the localized modes in one-dimensional photonic heterostructures under normal incidence are investigated. Each structure consists of two semi-infinite ...
Study of KCl + x% in and KCl + y% TlCl thin films
(1998-12-01)
The present work reports the study of KCl thin films doped with In+ or Tl+. Both systems show optical absorption bands similar to single crystals. As the impurity concentration increases, so does the absorption as also the ...
Evaluation of crystallized biosilicate in the reconstruction of calvarial defects
(Springer, 2015)
The objective of this study was to assess the bone repair process of crystallized Biosilicate in surgically created defects on rats' calvaria. This biomaterial was recently developed for odontological use. We used fifteen ...
Crystallization dynamics on curved surfaces
(Amer Physical Soc, 2013-07)
We study the evolution from a liquid to a crystal phase in two-dimensional curved space. At early times, while crystal seeds grow preferentially in regions of low curvature, the lattice frustration produced in regions with ...
Electrical properties of the SnO2-based varistor
(1998-12-01)
The non-linear electrical properties of CoO-doped and Nb205-doped SnO2 ceramics were characterized. X-ray diffraction and scanning electron microscopy indicated that the system is single phase. The electrical conduction ...
