A team of researchers has found evidence for a strange particle that, unusually, is likewise its very own antiparticle. It was first proposed 80 years back however now existence of it may be a reality.

The outcomes, published in the journal Science, were led by analysts from Stanford University in California and the University of California.

The idea of a particle having its own antiparticle was first presented in 1937 when Italian physicist Ettore Majorana (who strangely disappeared in 1938) first proposed the theory. 

He said that inside the class of fermions, which contain protons, electrons, and neutrons, a few particles must have their own antiparticles, which wound up known as Majorana particles.

 An antiparticle is a particle that has similar mass from the typical particle, yet a reverse electric or magnetic property. For example, the electron's antiparticle is the positron. In the event that the two go over one another, they obliterate one another. 

In this research, the team of physicists stacked thin movies of two quantum materials together and coordinated an electrical current through them in a chilled vacuum chamber. The best movie was a superconductor, and the last one was a magnetic topological insulator.

By sweeping a magnet over the stack, the group was then ready to modify the speed of electrons. At specific focuses, this activated what appeared to be Majorana quasiparticles to show in pairs alongside with electrons. One was constantly bounced away so that the flow of the individual quasiparticles could be measured.  

The specific sort of Majorana quasiparticle they think they've found is known as a "chiral" fermion, which moves along a one-dimensional way in one direction.

So the researchers are signifying to this as “smoking gun”sign of Majorana particles. It was at that point trusted that neutrinos may be their own antiparticles, however separate research is progressing to find out if that’s the case.

Stanford professor Shoucheng Zhan, a senior author on the paper, said:

"Our group anticipated precisely where to find the Majorana fermion and what to search for as it's ‘smoking gun’ trial signature. This discovery closes one of the most intensive searches in fundamental physics,, which crossed precisely 80 years."
