Light - what seems impossible to touch why is it liquid, like water?

Fluid properties are capable of flowing around objects, filling all gaps. As for light, it is a waveform (sometimes acting like an atom), moving in a straight line, then being stopped when encountering an obstacle.

Light cannot bend on its own, which is why you cannot observe the two sides and the back of an object, as well as the angle of turning on the roads. This is also the most fundamental difference between light and water.

The "liquid light" they create is a superfluid - no friction and viscosity.

However, in some extreme conditions, light can be as water-like, allowing it to bend itself "to flow" around the object. People call it "liquid light".

Experts say, the "liquid light" they create is a superfluid - no friction and viscosity, and is a form of matter in the "Bose-Einstein condensate" (Bose-Einstein condensate or BEC).

The problem arises where BEC (which is considered the fifth state of matter) is where conventional laws of physics transform into quantum physics. And it only appears when the temperature reaches "absolute zero" (0 degrees K or -273 degrees C), in other words extremely difficult.

Recently, however, researchers have found a way to bring matter to the BEC state under room temperature conditions. In other words, for the first time in the history of "liquid light" can exist so easily.

By combining light and matter , they formally created "liquid light" under normal conditions.

Specifically, the study was carried out by experts from the Institute of Nanotechnology CNR NANOTEC (Italy). By combining light and matter , they formally created "liquid light" under normal conditions.

"Most importantly at this work, we have demonstrated that superfluids can exist at room temperature, using light particles called photons " - Daniele Sanvitto said.

However, to create photonic particles is not simple, requires many tools to operate at the nanoscale. Sanvitto had to "pinch" a layer of 130nm thick organic molecules between two super-reflective mirrors, then fire a powerful laser.

"We can combine the properties of photons - such as mass and speed - with strong interactions with electrons in conventional molecules" - Stéphane Kéna-Cohen of the research team shared.

Difference between liquid (above) and superfluid (below).The liquid when blocked will form waves, while superfluid is not.

According to experts, this discovery has paved the way for the next study of hydraulic quantum. And not only that, photonic particles will be like the factors that make future technology evolve, especially in light-related areas like LED, Solar battery, or laser.

The study is published in the journal Nature Physics.
