The first two-dimensional superseded quantum gas in the laboratory.
Quantitative gases are ideal for analyzing small-scale interactions. Today, scientists are able to accurately control individual particles in very cold gas clouds in the laboratory, reflecting phenomena that cannot be seen in everyday life. For example, the individual atoms in the Bose-Einstein container are completely isolated. This means the same thing Atom It is present at each point in the condensate at any time.
Two years ago, a research team led by Francesca Ferlano, of the Department of Experimental Physics at Innsbruck University, and the first successful superpolitical state of the Austrian Academy of Sciences in Innsbruck were able to produce the most successful states in the world. Magnetic Atoms Quantum Gases. Magnetic interactions cause the atoms to organize themselves into droplets and adapt to normal conditions.
Matthew Norcia, of Francesca Ferlano’s team, says: “Normally, you think that every atom is in a specific drop. However, in the supersolyzed state, each particle is removed in all droplets at the same time, in each droplet at the same time. So, basically, you have a system with a series of very dense regions (droplets) that share all the same degraded atoms.
Although there is a spatial sequence, this unusual formation produces results such as non-conflict flow.
New metrics, new results to explore
So far, superpowered states have been observed in quantum gases as droplets. “We have now expanded this phenomenon into two dimensions, in collaboration with theorists Luis Santos at Innsbruck, in the University of Hanover and Russell Biss in Innsbruck,” said Matthew Norcia. Not only is this a modest improvement but it also expands research perspectives.
“For example, in a two-dimensional supersoleid system, one can study how a vortex is formed in the space between several parallel droplets.” Francesca Ferlano said: “These theoretical cycles have not yet been described, but they represent the necessary result of over-healing.” Nature’s experiments in this journal provide new opportunities for further exploration of the basic physics of matter.
A new field of research – supersocial
Predicted 50 years ago, high humidity has been tested extensively in excess helium. However, after decades of theoretical and experimental research, there is still no clear evidence of transparency in this system. Two years ago, research teams in Pisa, Stuttgart and Innsbruck succeeded for the first time in creating so-called supersoids of magnetic atoms in altruistic quantum gases. The basis for the new, growing field of supersolids is the solid poles of magnetic atoms, and their contact characteristics allow the mechanical conditions of this paradoxical quantum to be created in the laboratory.
