In recent years, active self-propelled particles have attracted growing interest from the scientific community. Examples
Vortex - a new state of active matter -demonstrated amazing behavior, as a result of which, instead of accelerated movement, groups of quasiparticles moved at a constant speed proportional to the applied force and in the same direction of the force. This behavior seems to violate Newton's second law.
"We were completely baffled to seehow these quasiparticles rotate within active matter, behaving like individual superparticles with surprising properties, including lack of acceleration when force is applied, and merging upon collision to form vortices of greater mass. These patterns have previously been observed in animals at different stages of evolution: from worms, plants, animals and insects to fish, but rather as single structures, rather than as a phase that borders other phases, reminiscent of gaseous and liquid normal matter.”
Professor Nikolai Brilliantov, who led the research at the University of Leicester
The world of active particles has many practicalapplications, including in the advanced fields of artificial intelligence, space data, and robotics. Since one of the possible practical applications of active particles could be self-assembly, experts at the University of Leicester agree that physicists should continue to push for discoveries based on simulation work. This ensures that, in real life, materials, substances and groups work in a reliable, expected and predictable manner without inevitable uncertainties.
