This is the first time, when scientists get Liquid Light at Room Temperature. This matter is both a superfluid, which has zero friction and viscosity, and a kind of Bose-Einstein condensate, mentions bizsiziz.com.
As we know the light acts like a wave, and sometimes like a particle, always travelling in a straight line. That’s why human’s eyes can’t see around corners or objects. (But under extreme conditions, light can also act like a liquid Liquid Light and actually flow around objects).
“The extraordinary observation in our work is that we have demonstrated that superfluidity can also occur at room-temperature, under ambient conditions, using light-matter particles called polaritons,” said lead researcher Daniele Sanvitto, from the CNR NANOTEC Institute of Nanotechnology in Italy.
“In this way, we can combine the properties of photons – such as their light effective mass and fast velocity – with strong interactions due to the electrons within the molecules,” said one of the team, Stéphane Kéna-Cohen from École Polytechnique de Montreal in Canada.
when it is normal condition the liquid flows, it creates ripples and swirls – but that’s not the case for a superfluid.
“In a superfluid, this turbulence is suppressed around obstacles, causing the flow to continue on its way unaltered,” said Kéna-Cohen.
With the word of researchers, the results cover the way not only to new studies of quantum hydrodynamics, but also to room-temperature polariton devices for progressive future technology, such as the production of super-conductive materials for devices such as LEDs, solar panels, and lasers.
“The fact that such an effect is observed under ambient conditions can spark an enormous amount of future work,” said the team.
“Not only to study fundamental phenomena related to Bose-Einstein condensates, but also to conceive and design future photonic superfluid-based devices where losses are completely suppressed and new unexpected phenomena can be exploited.”
