Physicists create a time quasicristal in a diamond

A Quasrystal is a solid formed by atomic patterns that are not repeated but arranged at a level. In practice, They are among the crystals and amorphous materials.

This may seem very abstract to people who are not the most profession, but know that Quasrystals means significant progress in quantum physics. And now this branch of science celebrates a new success: the creation of a new temporal quasrystal species in a diamond.

New Quasicristal

Researcher Guanghui He with his colleagues at the University of Washington, Quasicrystal for the first time in a diamond. This occurred after electric shock with diamonds laserThis has made the fixed standards of the non -repeated material.

Unlike traditional crystals such as diamonds or quartz with atomic structures that are spatially predictable, In this time, crystals remain smooth in space, but over time there is a periodic oscillation. This makes them four -dimensional crystals – the size of the three physical dimension plus time.

“This Quasrystals can store quantum memory for a long time, essentially hide it as quantum ram analogue. We are far from such a technology. He said.

What are the time Quasicerists?

Quasrystals was discovered in the 1980s by the Israeli physicist Daniel Shechtman, who won the Nobel Prize in Chemistry in 2011 in 2011. He fought for years to convince his colleagues that they really existed.

In an interview with G1, Carlos Basilio Pinheiro, a physicist of Minas Gerais Federal University, said that crystals were periodically formed by atomic clusters organized in space. The smallest crystal unit unit repeated in space is called cell. There are thousands of atoms inside.

Time Crystals recommended by American physicist Frank Wilczek (who won the Nobel Prize in 2004) They express a controversial concept to describe a new matter state. It is a material in which particles move with sequences that are not dictated with any external pushing time.

Quasrystals do not have unit cells. In addition, there is no repetitive pattern in three dimensions of the area. Although the Quasrystal structure is a descriptive mathematical formula, The “skeleton” of the material is different from a crystal because there is no repeated atomic set.

That is, Quasrystals is a place between a recurrent and regular atomic crystal and an amorphous material like glass where atoms are randomly regulated. There was even doubt that Quasrystals were extraterrestrial production, not by chance.

Therefore, the innovation here is the creation of the first kquasicristal of the first time created by the temporal patterns of the oscillation particles that contain structure but non -repeated particles.

Researchers used to do this laser Nitrogen serving to release too many carbon atoms in a millimeter -wide diamond piece. Thus, there was a place to “move üz under the quantum influence of the neighbors of the electrons.

This new discovery can promise to better understand the functioning of time crystals like themselves. Scientists argue that this may have practical practices in terms of potentially revolutionary metrology. Waiting to see.
