A recent study conducted by researchers at the University of Helsinki has shed light on the quantum state of a rotating superfluid and its ability to discharge in three different patterns. This groundbreaking research, published in the journal Physical Review Letters, reveals the complex behavior of quadruply quantized vortices in superfluids.
Superfluids, which occur near absolute zero temperatures, exhibit unique properties due to the absence of internal resistance such as friction. Unlike classical fluids, their behavior is governed by quantum physics. When a superfluid is spun, it should theoretically continue rotating indefinitely due to the absence of viscosity. However, experiments with helium at extremely low temperatures have revealed that the rotation eventually halts due to the quantization of vorticity.
In this new study, Dr. Xin Li from the University of Helsinki explored the splitting processes of quadruply quantized vortices at different temperatures. It was previously known that these vortices could split into smaller vortices, but this research demonstrates for the first time that temperature influences the specific splitting patterns.
Using the gauge/gravity duality or holography theory, which allows for a realistic examination of temperature’s impact, the researchers modeled the splitting processes. They discovered that there are three distinct ways in which quadruply quantized vortices can split, leading to three different patterns. Two of these patterns have been observed experimentally at low temperatures, while the third pattern may become visible at higher temperatures.
These findings provide valuable insights into the behavior of superfluids and expand our understanding of quantum phenomena. By studying the quantum state of rotating superfluids, scientists can further explore the fundamental principles that govern the behavior of matter at extreme conditions.
This research has important implications for various fields, including condensed matter physics and quantum mechanics, and opens up new avenues for studying the dynamics of superfluids. As scientists continue to delve into the quantum realm, we can expect further revelations about the intricate nature of these fascinating systems.
