Three scientists from the University of Chicago have recorded this number, and they believe that there can be material that can deliver electricity and energy with 100% efficiency – never lose heat and friction.


Achievement, posted on February 18th Physical Review b, Offers a completely new kind of framework that can be very useful in real-world technology applications. Although the prediction is based on the theory, attempts are being made to test it experimentally.

"We have tried to answer the really essential question of whether it is possible or not. We thought these two properties could be inappropriate in one material, ”said co-author and research advisor David Maziott, professor of chemistry and the James Frank Institute and an expert on molecular electronic structure. "It should be surprising that the two states have actually turned into quantum levels and thus strengthened each other."

Because uninterrupted energy is lost each year to power lines, engines and cars, scientists are keen to find more viable alternatives. "In many ways, this is the most important issue of the 21st century – how to generate and transfer energy with minimal losses," Maziott said.

We know that supercomputers – the kind of material that can last almost zero loss in electricity forever – have been around for over a century. For the past few years alone, scientists have been able to produce similar materials in the lab that can deliver almost zero energy loss, called the exciton condensate.

But both superconductors and exciton condensates are difficult materials to maintain and maintain – partly because scientists do not fully understand how they work and the theory behind them is incomplete. We know that both involve quantum physics.

UChicago graduate student Lian Sanger was amazed at how two states can be created in the same material. Maziott's group specializes in investigating the properties and structures of materials and chemicals and computation, so he began incorporating various combinations into a computer model. "We scanned a lot of possibilities, and then surprisingly, we found a region where both states co-exist." He said.

It seems that in the right configuration two states are actually collapsing – a quantum phenomenon in which systems are unconsciously connected. This leads to the notion that these two states are not connected and may open a new field of double-gas and Fermion pairs of condensates.

Using some advanced mathematics, they have shown that thanks to quantum enhancement, double condensates should theoretically exist even at the macroscopic size of the human eye.

"This implies that such condensates can be sold in new materials, for example, in a double layer of superconductors," Sagar said.

Scientists are working with experimental groups to determine whether the prediction can be achieved in real materials.

“Combining superconductivity and exciton condensates should be amazing for many applications. Electronics, Spintronics, Quantum Computing. ” – said Shiva Sapai, PhD student and third author. "Although this is a first step, it is very promising."
