چکیده
The stability of the bound states of the magnetic flux in a Josephson resistive lattices is investigated numerically. It is shown that for a simple relationship between the geometrical parameters of the lattice the range of bias current is the widest.

متن کاملMini-emulsion preparation, kinetics of reaction and physical properties of acrylic terpolymer lattices
In this study, stable lattices of terpolymer butyl acrylate, methyl methacrylate, and styrene were synthesized by a mini-emulsion polymerization technique using tert-butyl hydroperoxide TBHP/Fe2 /ethylenediaminetetraacetic acid/sodium formaldehyde sulfoxylate redox initiators at room temperature, and the kinetics of the reaction were studied. The reaction rate was obtained from periodic samplin...
متن کاملJosephson Current For a Graphene Nanoribbon Using a Lattice Model
A tight binding approach based on the Bogoliubov-de Gennes approach has been used to calculate the DC Josephson current for a lattice model for S-GNR-S junctions , for short junctions with respect to superconducting coherence length. We calculate the phase, length, width and chemical potential dependence at the Josephson junction and discuss the similarities and differences with regard to the t...
متن کاملNon-Abelian Josephson effect and half vortex of cold atoms in traps and microcavities
We investigate the non-Abelian Josephson effect in F=2 spinor Bose-Einstein condensates with double optical traps. We propose a real physical system which contains non-Abelian Josephson effect and has very different density and spin tunneling characters compared with the Abelian case. We calculate the frequencies of the pseudo Goldstone modes in different phases between two traps respectively, ...
متن کاملGeometrical Defects in Josephson Junction Arrays
Dislocations and disclinations in a lattice of Josephson junctions will affect the dynamics of vortex excitations within the array. These defects effectively distort the space in which the excitations move and interact. We calculate the interaction energy between such defects and excitations, determine vortex trajectories in twisted lattices, and discuss the consequences for experiment. Typeset...
