Topological superfluid defects with discrete point group symmetries

Nature Communications, 2022
Ordinary vortex line defects are well-studied across different physical systems. Here the authors demonstrate, in atomic spinor Bose–Einstein condensates, previously unobserved vortex line defects with discrete polytope symmetries, which are of interest ...

Line Defects in Quasicrystals

Crystals
The six-dimensional framework of the integral formalism for line defects (straight dislocations and line forces) in anisotropic elasticity has been extended to a 2n-dimensional integral formalism for line defects in quasicrystals (n=4,5,6 for one-, two-,

Line Defects in Two-Dimensional Dodecagonal Quasicrystals

Mathematics
In this work, line defects in two-dimensional dodecagonal quasicrystals are investigated. Using the ten-dimensional framework of the integral formalism of two-dimensional quasicrystals, the closed-form solutions for the displacement fields and stress ...

Effects of line defects on spin-dependent electronic transport of zigzag MoS2 nanoribbons

AIP Advances, 2016
The nonlinear spin-dependent transport properties in zigzag molybdenum-disulfide nanoribbons (ZMNRs) with line defects are investigated systematically using nonequilibrium Green’s function method combined with density functional theory.

Resonant tunneling in disordered borophene nanoribbons with line defects

npj Computational Materials, 2022
Recently, borophene has attracted extensive interest as the wonder material, showing that line defects (LDs) occur widely at the interface between $$\nu _{1/5}$$ ν 1 / 5 and $$\nu _{1/6}$$ ν 1 / 6 boron sheets.

Establishment of a human MYH6 compound heterozygous knockout hESC line to model cardiomyopathy and congenital heart defects by CRISPR/Cas9 system

Stem Cell Research, 2021
MYH6 encodes the alpha heavy chain subunit of cardiac myosin. Mutations in MYH6 cause cardiomyopathy and congenital heart defects. However, due to embryonic lethality in MYH6 knockout mice, the precise roles of MYH6 in cardiomyopathy, congenital heart ...

Study of line defects in infinite networks of resistors

New Journal of Physics
We study infinite resistor networks perturbed by line defects, in which the resistances are periodically modified along a single line. Using the Sherman–Morrison identity applied to the lattice Laplace operator, we develop a general analytical framework ...

Atomic study of the trapped and migration patterns of point defects around screw dislocation in tungsten

Nuclear Materials and Energy, 2023
The interaction of 1/2 〈111〉 screw dislocation and point defects, including vacancy and self-interstitial atom (SIA), was investigated by molecular dynamics (MD) simulations.

Atomistic model of metal nanocrystals with line defects: contribution to diffraction line profile

Frontiers in Materials, 2015
Molecular Dynamics (MD) was used to simulate cylindrical Pd and Ir domains with ideal dislocations parallel to the axis. Results show significant discrepancies with respect to predictions of traditional continuum mechanics.
