Many phenomena from nature bear witness to symmetry in their dynamic development, which helps researchers better understand the internal mechanism of the system.
In quantum physics, this symmetry is not always achieved in laboratory experiments with lithium atoms through the cold.
In the world of classical physics, the ideal gas energy increases in proportion to the pressure applied, which is a direct consequence of scale symmetry, and so does the large-scale invariant system. In the world of quantum mechanics.
However, interactions between quantum particles can be so strong that this classical symmetry is no longer applied.
The researchers studied the behavior of ultracold, ultra-liquid lithium-atom gas. When the gas is out of balance, the gas starts to expand and contract repeatedly during breathing. Unlike classical particles, these quantum particles can bind in pairs, and as a result, superfluidity becomes stiffer because it is denser.
A group of researchers observed this deviation from classical rock symmetry, directly verifying the quantum nature of this system.
The researchers report that this effect provides a better idea of the behavior of systems with properties similar to graphene or superconductors, which do not show electrical resistance when cooled at certain critical temperatures.
