Scientists propose a new elementary particle

Scientists discovered a new type of elementary particle

A study in Nature reported that scientists have recently discovered a new type of elementary particle. Weyl Type II, it was named to distinguish it from the previously known Weyl fermion particles. Possessing a special effect, it is possible to transfer matter from insulator to conductor and vice versa when there is a magnetic field effect , Weyl Type II, if it exists, can produce semiconductors that are more effective. superior in future electronic devices.

Primary particles in nature are microscopic particles whose structures and components have never been discovered. That means we temporarily consider them to be identical and cannot be further separated. Modern physics divides elementary particles into two types of fermions and bosons . Boson particles can be mentioned as: photon, phonon, higgs . Fermions such as quark, electron, neutrion .

The proposed new Weyl Type II is one of the future fermions.

Besides the particles that were found, scientists also used mathematical models to predict more other types of particles. These particles will become the targets of experimental science, if discovered, they will be present in the standard model. It is possible to mention that the particles that went from realistic math to Higgs were proposed in 1964 and discovered in 2012, the Weyl fermion is predicted in 1929 and has just been discovered in early 2015.

And to add to the 2015 waiting list, the newly proposed Weyl Type II is one of the future fermions. The mathematical model shows that it exists in a material called tungsten ditelluride (WTe2) . This is a kind of semi-metallic material with "hybrid" properties between metals and semiconductors.

Weyl Type II can cause the effect of turning a semi-metallic material into superconductivity or completely insulating depending on the direction of current flowing inside it. Unlike old Weyl particles, Weyl Type II can survive in a wide temperature range at its lowest energy state. This opens up an opportunity for it to "infect" a host material with adjectives and superconductivity.

The authors of the study created tungsten ditelluride crystals in the laboratory. Later, they built a model containing all the basic particles included in it including the Weyl fermion. Accidentally the data indicates that Weyl Type II may exist. Comparatively similar to electrons, scientists predict Weyl Type II is an important fundamental particle in solids. Only they hardly cause interaction.

Although not yet directly observing this new fermion, scientists' prediction will "line up" Weyl Type II into a list of particles waiting to be discovered. Weyl Fermion was predicted in 1929 and was only found earlier this year. So maybe we have to say goodbye to the news about Weyl Type II for a long time and leave the job to the scientists.
