We initially understand the world by our senses. And the quantum world stays largely inaccessible to those senses. Therefore our issue in understanding it. However issues could possibly be altering now that physicists have managed to “contact” a quantum object.

[EN VIDÉO] Quantum mechanics defined in video What’s quantum mechanics? What’s it for ? What’s his area of examine…

The world of quantum physics is unusual, to say the least. So totally different from ours that we will simply think about it being intangible. However physicists like challenges. That’s why they seemed for a solution to the query that was on the lips of all scientists – and maybe a few of you who’re curious -: “What does it really feel like to the touch a quantum object?” »

Touching a quantum superfluid with a probe

Physicists from Lancaster College (Nice Britain) report right this moment within the journal Nature Communication how they (virtually) succeeded in touching a superfluid fabricated from helium 3 (3He). To be able to make it superfluid, researchers need to preserve the helium in query at a temperature of round one ten-thousandth of a level above absolute zero. Due to this fact, it’s not possible to truly put a finger in it.

The researchers due to this fact carried out a posh protocol. And at last they managed to dip a finger-sized probe into it. A probe whose aim was to transmit thermodynamic info to physicists. It labored. They concluded that many of the superfluid behaves like a vacuum. So for those who have been to dip your finger into it, a two-dimensional floor would kind round it and the interplay would due to this fact solely happen with a two-dimensional liquid.

A two-dimensional impression for the superfluid

It’s unusual ? Sure. However it’s quantum… In any case, this work not solely satisfies a little bit of our curiosity, but in addition offers a brand new imaginative and prescient of this superfluid, which has already been studied intimately by scientists. On the lowest temperatures and energies, the helium-3 superfluid is thermomechanically two-dimensional. And the implications may transcend the bounds of quantum physics and upend particle physics and even cosmology.
