We describe the fabrication and construction of a setup for creating lattices of magnetic microtraps for ultracold atoms on an atom chip. The lattice is defined by lithographic patterning of a permanent magnetic film. Patterned magnetic-film atom chips enable a large variety of trapping geometries over a wide range of length scales. We demonstrate an atom chip with a lattice constant of 10 μm, ...
Nienhuis’ truncated O(n) model gives rise to a model of self-avoiding loops on the hexagonal lattice, each loop having a fugacity of n. We study such loops subjected to a particular kind of staggered field w, which for n → ∞ has the geometrical effect of breaking the three-phase coexistence, linked to the three-colourability of the lattice faces. We show that at T = 0, for w > 1 the model flows...
The post-entry restriction factor Trim5α blocks infection of retroviral pathogens shortly after the virus gains entry to the cell, preventing reverse transcription and integration into the host genome. Central to the mechanism of restriction is recognition of the lattice of capsid protein that forms the inner-shell of the retrovirus. To recognise this lattice, Trim5α has been shown to assemble ...
Quadrature amplitude modulation filter-bank multicarrier (QAM-FBMC) is a promising technology for future wireless communications systems. However, the intrinsic interference observed at receiver can be source of problems. In order to overcome interference, in this paper, we propose QAM-FBMC system with hexagonal lattice structure, which call HQAM-FBMC. We also new prototype filter design, speci...
In this research nickel zinc ferrite nanoparticles with composition of Ni1-xZnxFe2O4 (where x=0, 0.3, 0.7, 1) were synthesized by a sol-gel method at 600 °C for 5 hours. The structure of nanoparticles was studied using X-ray diffraction pattern. The lattice parameter of ferrite nanoparticles was calculated and indicates lattice constant of nanoparticl...
Equivariant bifurcation theory has been used extensively to study pattern formation via symmetry–breaking steady state bifurcation in various physical systems modeled by E(2)– equivariant partial differential equations. Much attention has focussed on solutions that are doubly–periodic with respect to a square or hexagonal lattice, for which the bifurcation problem can be restricted to a finite–...
