Information carrying could be improved through hopfions
The knot theory originates in Lord Kevin's model proposed in 1867 that atoms are made of vortex rings or knots. Although the hypothesis was proved incorrect, the knot theory has since then proliferated in both mathematics and physics. One peculiar ca.....»»
Novel single-crystal production method opens up promising avenues for studies in solid-state physics
Single crystals are materials in which the crystal lattice is continuous and unbroken to the edges of the sample, with no grain boundaries. The atoms occupy regular positions, which are repeated indefinitely in space. While polycrystals are made up o.....»»
