A research team has created and observed quasiparticles called 3D hopfions at the nanoscale (billionths of a meter) in a magnetic system. The discovery could advance high-density, high-speed, ...

In a recent theoretical study, scientists discovered the presence of the Hopfion topological structure in nano-sized particles of ferroelectrics -- materials with promising applications in ...

(Nanowerk News) Exotic magnetic structures such as skyrmions are also known as topological particles. Because they can be easily moved within a crystal, they are envisioned as promising information ...

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 ...

Scientists find a unique knotted structure — one that repeats itself throughout nature — in a ferroelectric nanoparticle, a material with promising applications in microelectronics and computing. Just ...

(Nanowerk News) A decade ago, the discovery of quasiparticles called magnetic skyrmions provided important new clues into how microscopic spin textures will enable spintronics, a new class of ...

Just as a literature buff might explore a novel for recurring themes, physicists and mathematicians search for repeating structures present throughout nature. For example, a certain geometrical ...
