Tokyo researchers successfully verified the superconductivity of Bose-Einstein condensate

Text/Chen Gen Superconducting material refers to a conductor whose resistance is zero at a certain temperature.
In addition, superconductors not only have the characteristics of zero resistance, but also have complete diamagnetism.
Since the discovery of superconducting materials in 1911, they have received attention and research from scientists.
Currently, powerful superconducting magnets are already key components of maglev trains, magnetic resonance imaging (MRI) and nuclear magnetic resonance (NMR) machines, particle accelerators and other advanced technologies, including early quantum supercomputers.
Superconductors, as a material that does not have any resistance to the flow of current, are obviously extremely useful for the future of electronics.
Now, engineers at the University of Tokyo have successfully used a state of matter called Bose-Einstein Condensate (BEC) to create a superconductor.
It is worth mentioning that this is the first time in history.
There are three well-known states of matter in people's daily life: solid, liquid and gas.
The fourth state of matter is plasma.
Plasma is like a gas.
All of its constituent atoms are decomposed, leaving behind a bunch of superheated subatomic particles.
However, in addition to the four states, there is also a fifth state of matter that people are not familiar with, including the Bose-Einstein condensate (BEC), which is still being understood and explored by scientists.
Bose-Einstein condensate (BEC) is a unique state of matter because it is not composed of particles, but of waves.
When they cool to near absolute zero, the atoms of certain substances will become blurred in space.
This smearing will increase until the atoms (now more like waves than particles) overlap and become indistinguishable from each other.
The resulting material behaves like a single entity with new properties that were previously lacking in solid, liquid, or gaseous states, such as superconductivity.
For a long time, superconducting BEC is only theoretical, but now, in a new study, researchers in Tokyo have demonstrated the superconductivity of Bose-Einstein condensate-which has never been done in experiments before.
It's verified.
This result was achieved by using a cloud of iron and selenium atoms to create a Bose-Einstein condensate.
The key to this discovery comes from the overlap with a similar form of substance, which is called the Bardeen-Cooper-Shrieffer (BCS) system.
Bose-Einstein condensate, BCS is also formed by cooling atomic clouds to almost absolute zero, but the difference here is that when they do, the atoms slow down and line up in a row.
This means that electrons can pass through them more easily, thereby achieving superconductivity.
The researchers said that demonstrating the superconductivity of BECs is only a means to an end, and they hope to be able to explore Find the overlap between BECs and bcs, although this is very challenging.
Although this discovery does not have any direct application to the general public, deepening people's understanding of this phenomenon will only help scientists create better superconductors in the future.
This in turn can lead to faster and more efficient electronic products.
The research has been published in the journal "Science Advances".
