Bird overgrowth can also be seen as a breakdown of symmetry: Instead of flying directly, they connect like spinners in a magnet. But there is an important difference: Ferromagnetic phase shifts are easily explained using statistical changes because they are the same system.
But birds — and cells, bacteria, and vehicles in the street — add new energy to the system. “Because they have a source of internal energy, they act differently,” Reichhardt said. “And because they do not conserve energy, it seems strange, according to the plan.”
Above Quantum
Hanai and Littlewood began their investigation into the BEC sub-sector change by considering the proposed phase shift. Consider water: Although liquids and vapors look different, Littlewood said, there is no difference between them. Mathematically, during the transition, the two countries are unknown. In a system in equilibrium, this principle is called complex principle.
Complex events are ubiquitous — in cosmology, extremely powerful physics, even in natural systems. But in all of these examples, researchers have not found a good example of condensates that are produced when quantum-type compounds are connected to the environment, moving continuously and pumping.
Hanai and Littlewood doubt that the main points and the special points should share some important details, even if they come from different sources. “Highlights are an interesting mathematical phenomenon,” says Littlewood, “where you cannot tell the difference between the two. The same thing happens in these polariton systems. ”
He also knew that under mathematical terms, laser — technically state-of-the-art and polariton-exciton BEC had similar equations. Mu paper published in 2019, the researchers linked the dots, and provided a new and, more important, global approach to the unique principles of transforming digital components.
“We believe this was the first manifestation of this change,” Hanai said.
At about the same time, Hanai said, he realized that even though they study quantity, their equations do not follow quantum mechanics. Did what they were learning also affect the big and the strange? “We began to question this theory [connecting a phase transition to an exceptional point] can be reused by old habits. ”
But to run the idea, they need help. They approached Vitelli and Michel Fruchart, a postdoctoral researcher at the Vitelli lab, who studies foreign phenomena in ancient sites. Their work extends to material things, which are rich in inconsistencies; for example, they can show different patterns when pressed on one side or the other and can also show specific points.
Vitelli and Fruchart were immediately impressed. Were some of the international standards taking place in polariton condensate, an important law regarding systems in which energy is not stored?
Log in to Sync
Now in the quartet, the researchers began to look for points that facilitate the link between inconsistencies and phase changes. For Vitelli, that means thinking with his hands. They have a tendency to create body-shaped systems to reflect complex, abstract events. In the past, for example, they used Legos to make lattice which is a high-performance device that moves differently on the edge than on the inside.
“Even though what we’re saying is fictional, you can show it with play,” he said.
