The researchers split the indivisible electron on the quasiparticles


We used to talk about electrons as indivisible building blocks of atoms, subatomic elementary particles smaller type without their components. However, according to new information of Swiss and German researchers, published this week in the scientific journal Nature, we are deeply mistaken. For the first time, scientists have been able to record observations of the electron, which is split into two distinct quasi-particles, and each particle at the same time took over the various features of the original electron.

Using samples of copper-oxide composition - Sr2CuO3, the researchers separated some of the electrons belonging to the copper atoms from their orbits and put them in a higher orbit, manipulating them using X-rays. After placing them in a higher - and at a higher rate - orbit of the electrons have been split into two parts, the first part was called spinon, who took the rotation of an electron with itself, and the other named obitron, it suffered an orbital electron momentum.

The rotation and orbit - at least as we imagine them - initially applied to each particular electron. Thus, the fact that they have been separated, is quite essential. And while researchers have thought some time ago that this kind of division could be theoretically achieved, they had a hard time proving it by experience to date. This is - a reminder that at the quantum level, there are still things that are, more or less, are a mystery to us.

"It has been known for some time that the special materials, the electron can in principle be split," says Jeroen van den Brink, who heads a team of theorists in Dresden, IFW, "but until now the empirical evidence of this separation into independent spinon and orbiton was not enough . Now that we know exactly where to look for them, we have to find these new particles are still in many materials. "

But it’s not all that was seen. This particular observation of electron split could be unusual values in the field of high-temperature superconductivity. Understanding the way in which electrons can dissolve into a quasi-particle, can improve our overall understanding of the electron and the way he moves, and thus help us find new ways of moving electrons - and therefore electricity - on any conductors, without losing a lot of its potential to all kinds of losses.
