The team constructed a bespoke cryogenic system capable of containing several liters of superfluid helium at temperatures lower than -271 °C. At this temperature liquid helium acquires unusual quantum properties. These properties typically hinder the formation of giant vortices in other quantum fluids like ultracold atomic gases or quantum fluids of light, this system demonstrates how the interface of superfluid helium acts as a stabilizing force for these objects.
Researchers uncovered intriguing parallels between the vortex flow and the gravitational influence of black holes on the surrounding spacetime. This achievement opens new avenues for simulations of finite-temperature quantum field theories within the complex realm of curved spacetimes.
